Enrolling in a course lets you earn progress by passing quizzes and exams. of the polypeptide. In agreement ESR experiments show no evidence for phosphate ionization in DNA after gamma irradiation [10, 101]. Iridoids employed for the synthesis of new analogues of carbocyclic nucleosides are aucubin, catalpol, anthirrinoside, geniposide, scutellarioside, loganin, and finally harpagide. It is the conjugate base of the hydrogen phosphate ion H(PO4)2, which in turn is the conjugate base of the dihydrogen phosphate ion H2(PO4), which in turn is the conjugate base of orthophosphoric acid, H3PO4. (5) Additionally, the positive charge on the head group is able to bind to a variety of signaling proteins and balance local negative charge on the membrane. Carboxyl Group Structure & Examples | What is a Carboxyl Group? Part of figure 25-5. Other electrophoretic parameters, such as applied field strength and temperature, have an effect on the mobility of the different chain length nucleic acids and on the separation efficiency. Nevertheless, the corresponding potential use of nucleosides in therapy is not simple due to several factors: Many nucleoside analogues are not effectively phosphorylated by cellular kinases during the hydrolysis of the nucleoside-base bond C1-base, consequently the C1C6 bond of the furan ring opens, and the resultant metabolites (especially those not identified) can be potentially toxic. Phosphate is represented with a formula of chemistry as PO43-. $148.50. Mining operations processing phosphate rock can leave tailings piles containing elevated levels of cadmium, lead, nickel, copper, chromium, and uranium. Regardless of the length of the aliphatic tail group the hydrophilic carboxylic acid group will have a pKa around 4.0, which means that under physiological conditions, the majority of fatty acids will have a negative charge of -1. IAA is a type of plant auxin and has great potential as a prodrug or as a cosmetic or dermatological ingredient. When it gets joined to the growing strand of DNA (or RNA), two of its phosphates are lost, and the remaining one attaches to another nucleotide's sugar. PA's greatest role is in the biosynthesis of triacylglycerols and other phospholipids, as its structure serves as the backbone these compounds. This is because the carboxyl and amino groups of serine have pKas of 2.21 and 9.15, respectively, so that the carboxyl group will be have a -1 charge at physiological pH; the reverse will be true for the amino group. Welcome to the site, hope to see you around! The phosphate moiety exhibits several different levels of protonation, depending on the pH. A phosphate group is just a phosphorus atom bound to four oxygen atoms, but it has many important roles. Many phosphates are soluble in water at standard temperature and pressure. Try refreshing the page, or contact customer support. Although comprising only about 5% of total lipid content in membranes, phosphoinositols (PIs) are concentrated on the inside leaflet of the lipid bilayer where they play crucial roles in cellular signaling, protein binding, and membrane dynamics. Because of the unique ionization properties of its head-group, which can deprotonate to a -2 charge in the process of forming an intermolecular hydrogen bond, it serves a crucial role in the binding of basic protein and small molecule compounds (2). The spherical structure is favored by fatty acids because the cross-sectional area of the head group is larger than that of the tail, forming a conical shape. It can further result in a bone disease. source@https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-013-electromagnetics-and-applications-spring-2009, status page at https://status.libretexts.org, David L. Nelson & Michael M. Cox, "Principles of Biochemistry, fourth edition." Why does phosphate have a charge of 3? Free amine groups as present in phosphatidylserine or phosphatidylethanolamine show a single sharp absorption band at 1075cml. $25.00 shipping. Ourines in DNA | Structure, Examples & Rings. Is the amplitude of a wave affected by the Doppler effect? Their presence in the neighborhood of phosphate residues (or of Kdo in LPS) may be considered as a regulating factor, controlling the electrostatic interaction of negatively charged residues (phosphate) with such bivalent cations as Ca2+ or Mg2+ of the medium. Chia-en A. Chang, Yu-ming M. Huang, in Annual Reports in Computational Chemistry, 2013. The introduction of a phosphate group generally carries a 2 charge at physiologically pH. In order to measure the enhancement in stability due to LDH interaction, IAA, IAA-LDH, and IAA-ZBS were dispersed in water and their concentrations were monitored for 10days. Get unlimited access to over 88,000 lessons. Around pH 9.8 (mid-way between the second and third pKa values) the monohydrogen phosphate ion, [HPO4]2, is the only species present. In this lesson, learn what a phosphate group is, what a phosphate group looks like, and the phosphate group formula. An error occurred trying to load this video. Despite this interesting method of resolution of mixtures of iridoids and the pharmaceutical interest addressed to iridoids, there are few scientific papers which face this kind of purification way [97158]. 6.7. AMP, ADP, and ATP) and in DNA and RNA. The sugar-phosphate groups form a backbone in the single strand of DNA. Can dialogue be put in the same paragraph as action text? Conversely, the separation and analysis of nucleic acids can be tuned by selection of an appropriate matrix and composition (Table 1). When solvation and counterion effects are accounted for to model the environment of the phosphate group, as recently suggested in an ab initio study of the properties of phosphate anions [120], this ionization potential significantly increases to 10.9-11.9eV [116, 119]. This is a concern because radioactivity can be released into surface waters[14] from application of the resulting phosphate fertilizer. A convergent synthesis could be schematized in two main steps; the first step deals with a modification of the iridoid backbone to give the new carbocyclic intermediate; the following step is the heterocyclic base link to the new carbocyclic backbone. Note that these esters are also acids. Legal. The replacement of oxygen by different atoms can greatly affect the metabolic stability and the ability to interact with biomolecules (by H-bonds or other noncovalent interactions) [159]. Smaller deposits are located in Montana, Tennessee, Georgia, and South Carolina. A role in stabilization of 2'-deoxyribonucleotides. J.H. The ester carbonyl frequency and bands between 670 and 1050cm1 may shift due to the variations in the crystal structure arising from different polymorphs. Structural differences in the interlayer orientation result from the different charge densities of the ZBS and ZnAl-LDH (5.8e/1002 and 5.0e/1002 for ZBS and LDH, respectively).63 Consequently, ZBS can contain more IAA molecules per unit charge than LDH, resulting in a more compact molecular packing with a smaller tilting angle. Phosphatidylethanolamine (PE) is the second most abundant phospholipid and is comprised of the typical phosphatidic acid with an additional head group component, namely ethanolamine. Proteins get deactivated when the phosphate group is removed. The pKa values are the pH values where the concentration of each species is equal to that of its conjugate bases. Sulfhydryl Group | Structure, Formula & Examples. For the organophosphorus derivatives, see, InChI=1S/H3O4P/c1-5(2,3)4/h(H3,1,2,3,4)/p-3, Except where otherwise noted, data are given for materials in their, Kipton J. Powell, Paul L. Brown, Robert H. Byrne, Tams Gajda, Glenn Hefter, Staffan Sjberg, Hans Wanner (2005): "Chemical speciation of environmentally significant heavy metals with inorganic ligands. After entering the cells, these drugs are converted into the nucleotides by kinases or degraded. Along with natural products belonging to the Hypericum genus, another natural interesting source of anti-HIV agents is given by iridoids. These interactions, therefore, appear to be of great importance for the stability and function of the bacterial outer membrane. There are 3 hydrogens in phosphoric acid, each of them leaves as: 1 H joins with 3' -OH of previous nucleotide to form $\ce{H2O}$ during DNA replication. The phosphate group is a phosphorous atom bonded to four oxygen atoms. The degree of metastable decay in MALDI is matrix dependent, and is mostly observed when a hot matrix, such as -cyano-4-hydroxycinnamic acid is utilized. Removal of one or two protons gives the dihydrogen phosphate ion [H2PO4] and the hydrogen phosphate ion [HPO4]2 ion, respectively. Its palatability for children is improved by using a suspension of the palmitate ester. The phosphodiester bond will always link the 5-carbon of one deoxyribose (or ribose in RNA) to the 3-carbon of The addition of one phosphate group leads to a mass increase of 79.97986 a.m.u. The structural complexity of the membrane bilayer goes beyond a single type of phospholipid molecule. Shi et al.55 intercalated the large protein bromelain, a mixture of proteolytic enzymes derived from pineapples, into LDHs by utilizing a reconstruction method in which calcined MgAl-LDH was mixed with bromelain/phosphate buffered saline (PBS). [5] Injectable phosphates can only be handled by qualified health care providers.[5]. This complex helps stabilize the DNAwhich as important in several ways Phosphate groups are common in nucleic acids and on phospholipids (the term Vanillic acid (VA: 4-hydroxy-3-methoxybenzoic acid), which is frequently used as a flavoring or food additive, has been successfully intercalated into ZnAl-LDH with various metal ratios.61 Data from X-ray diffractometry and infrared spectroscopy show that LDHs can well preserve VA molecules via electrostatic interactions, regardless of the metal ratio used. Most frequently, this is accomplished by electrophoresis through a sieving medium, i.e., a gel, through which small molecules will pass more easily and larger ones will pass more slowly, due to the combined effects of sampling a greater fraction of the gel space and hindered transport (volume exclusion) effects. While most lipids are composed of non-polar hydrocarbon structures, other lipids can contain positively and/or negatively charged elements, the nature of which imparts particular physical properties that give charged lipids structural and functional versatility. Another folate derivative, methotrexate (MTX: (2S)-2-[(4-{[(2,4-diamino-7,8-dihydropteridin-6-yl)methyl] (methyl)amino}phenyl)formamido] pentanedioic acid), is known to act as a folic acid antagonist and inhibits the proliferation of certain cancers by regulating the biosynthesis of thymidylate.56,57 Unfortunately, these are quite unstable in biosystems, with short plasma half lives of 6.2h and 315h (depending on dose) for folinic acid and MTX, respectively. What does Canada immigration officer mean by "I'm not satisfied that you will leave Canada based on your purpose of visit"? The addition of one phosphate group leads to a mass increase of 79.97986 a.m.u. Figure 2. Besides DNA, large biopolymers such as polysaccharides and proteins can be intercalated into LDHs. The phosphate ion has a molar mass of 94.97g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. Create your account. Inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry.[2]. Similar thermal stability was observed with GLA intercalates; the intercalated GLA preserved 50% of its fatty acid moieties after 28days at 50C, whereas all unprotected GLA molecules were oxidized after 14days in the same chamber. With fatty acids, it makes the phospholipid bilayer that holds our cells together. Each phosphate is a PO 4 (oxygen has a charge of -2 and there are 4 of them, for a total of -8, and P has a charge of +5, so the net charge on the phosphate group is -3. DNA-LDH or DNA alone, with the same initial optical density of 0.4 at 260nm, were identically treated with 192 units of DNase I and DNA degradation by DNase I was estimated by the change in optical density at 260nm recorded as a function of time (Figure 3). Both the electrostatic stabilization and the intermolecular hydrophobic interactions of fatty acid packing are considered to play important roles in the observed enhancement in thermal stability. Hydrolysis of diloxanide furanoate in the body is required for it to be effective against intestinal amebiasis. DNA is basically a polymer of nucleotides. Figure 3. As suggested by Amaral et al. This sheet is so stable that it's what our cells are made of! Two enzymes that are commonly used for dephosphorylation reactions are calf intestinal alkaline phosphatase (CIP)115 or bacterial alkaline phosphatase (BAP);116,117 in both cases, the reaction is typically allowed to proceed for 30 min at 37 C. Gel purification followed by DNA precipitation is once again required following dephosphorylation. Should the alternative hypothesis always be the research hypothesis? The synthesis of new carbocyclic nucleoside analogues produces two important contributions: (1) it provides potential new drugs to be used as therapeutic interventions in combination therapies with other drugs and (2) libraries analogues with antiviral activity can be used to study the SAR, in order to understand the role they play during the biochemical processes. The intercalation of therapeutic genes, such as antisense oligonucleotides, into LDHs has also been reported.13 Thyveetil et al.53 computed the stability of DNA-LDH intercalates utilizing molecular dynamics simulations and showed that the phosphate backbone exactly aligns with the lattice of the trivalent ions. By convention, they are usually drawn in their fully deprotonated states. At high enough concentrations, fatty acids will aggregate to form spherical structures called micelles, which are energetically favorable structures that increase the entropy of water by minimizing water clathrate formation around the hydrophobic regions. Nucleotides show a hydroxymethyl chain linked on C-4 with the phosphoester of phosphoanhydride derivatives as mono-, bi-, or triphosphate attached to position C-5. Others include palmitic acid, a common N-linked acyl chain of SM in mammalian peripheral cells, and stearic acid, which is more common to neuronal tissues. (8). ATP transfers phosphate groups to alcohols in many enzyme-catalyzed metabolic reactions. (A) Retention of IAA in aqueous solution of IAA (squares) and in IAA-ZBS (circles) and IAA-ZnAl-LDH (triangles) nanohybrids at 42 C in aqueous solution. 6.7) [99,100]. The two bonds between the phosphates are equal high-energy bonds that, when broken, release sufficient energy to power a variety of cellular reactions and WebThe phosphate group attached to the 5' carbon of the sugar on one nucleotide forms an ester bond with the free hydroxyl on the 3' carbon of the next nucleotide. An adenine nucleotide is joined to a cytosine nucleotide. This removes a charge from the functional group so it becomes R-PO4 2- as opposed to the phosphate ion which has a charge of 3- . And of course, histones wouldn't be able to join DNA and exert their key regulating functions. Therefore, it can be concluded that the intercalated DNA becomes more twisted than free DNA in order to fit into the available area in the LDH lattice (Figure 2(a)). The spectrum of a solid phospholipid may show fine structure at low temperatures, which disappears on heating. Chloramphenicol is bonded in the ester through its primary hydroxyl group. These factors often complicate the analysis and interpretation of data. Connect and share knowledge within a single location that is structured and easy to search. Similarly, an MS-based phosphatase assay is a useful tool to identify phosphopeptides in crude peptide mixtures generated by enzymatic proteolysis of phosphoproteins [13,34,35]. When phosphoric acid is deprotonated, its conjugate base is the phosphate ion. The introduction of a phosphate group generally carries a 2 charge at physiologically pH. Generally, hydrogen is not shown in DNA structure. WebValence U1-12RT 12.8v 40Ah Rechargeable Lithium Iron Magnesium Phosphate Battery. Both phosphate groups of lipid A at C-1 and C-4 may carry (polar) substituents, although examples in which the phosphate groups are free are known. Many proteins are either activated or deactivated by the addition or removal of a phosphate group from their aminoacids. The carbon atom chain to the right of the carbonyl group is part of the acid. All other trademarks and copyrights are the property of their respective owners. Phosphoserine and phosphothreonine residues undergo partial gas phase -elimination of phosphoric acid (H3PO4, 98Da), in MALDI-TOF-MS and ESI-MS resulting in conversion into dehydroalanine residue (69Da) and dehydroaminobutyric acid residue (83Da), respectively. [16], The largest importers in millions of metric tons of phosphate are Brazil 3.2, India 2.9 and the USA 1.6.[17]. A partial loss of phosphate (HPO3, 80Da) is seen in MALDI reflector TOF MS in the case of tyrosine phosphorylated peptides [30,36]. The sodium, potassium, rubidium, caesium, and ammonium phosphates are all water-soluble. Won et al.60 have reported that the intercalation of CLA and GLA into zinc hydroxide through coprecipitation greatly enhanced their thermal stability during storage. I am studying chemistry in High School and I am studying my ions (Because I failed too in the beginning, oops) and I have a question on this reasoning: In Phosphate Another example of protein intercalation into LDHs was provided by Rahman et al.18 They successfully incorporated lipase molecules onto LDH surfaces through physical and chemical adsorption which included electrostatic interactions. A normal functioning kidney should keep the phosphorus levels in a specific range despite any variation in the dietary phosphorus intake. A consequence of this behavior is that for high molecular weights, the grouped of the DNA chain no longer samples a distribution of pore space, and the mobility becomes independent of chain length. WebThe sugar-phosphate backbone has a negative charge that allows DNA to easily dissolve in water and is also used by proteins that bind the DNA. Dystopian Science Fiction story about virtual reality (called being hooked-up) from the 1960's-70's, New Home Construction Electrical Schematic. WebRevolutionary, reliable green energy, were Battle Born Batteries. Rietschel, in Advances in Carbohydrate Chemistry and Biochemistry, 1994. The presence of a negative charge causes phosphates to act as a nucleophile; it seeks a positive charge, therefore it is always found bound to other atoms or molecules. The result is a free-floating phosphate plus ADP, or adenosine diphosphate (meaning it only has two phosphate groups). The various metaphosphate ions (which are usually long linear polymers) have an empirical formula of (PO3) and are found in many compounds. Even though the phosphate group in the DNA backbone offers a potential hole localization site, there is no experimental evidence for phosphate-centered radical cations with low LET radiations [113]. Given that the thickness of a brucite-like LDH sheet is 4.8, the gallery heights are estimated to be 17.1, 14.3, and 15.1 for folic acid-, folinic acid- and MTX-LDH intercalates, respectively. There exist a variety of phospholipids with varying head groups and hydrocarbon tails. WebDNA contain negative charge because the presence of phosphate group. As with any molecule, the formation of a charge requires the inclusion of an ionizable element, most often covalently bound to the parent compound. Phosphates are used for the activation of proteins to make them perform specific functions. That's why ATP is used as an energy carrier all over the cell. Area provided per unit charge by LDH lattice: therefore area unit charge=8.323=24.92/e. For example, as part of the metabolism of glucose the hydroxyl group at C-6 is phosphorylated in a reaction with ATP to give glucose 6-phosphate and ADP. Roth, in Encyclopedia of Analytical Science (Second Edition), 2005. On the other hand, the physical properties of the different head groups dictate the interactions of each phospholipid with the aqueous environment, and resulting in the movement of the lipids across the bilayer in both the vertical and horizontal directions, continuously changing its shape and phospholipid organization. The conjugate base of phosphoric acid that is deprotonated is called a phosphate ion or inorganic phosphate. [9] Phosphorus comprises 0.1% by mass of the average rock[10] (while, for perspective, its typical concentration in vegetation is 0.03% to 0.2%),[11] and consequently there are quadrillions of tons of phosphorus in Earth's 31019-ton crust,[12] albeit at predominantly lower concentration than the deposits counted as reserves, which are inventoried and cheaper to extract. [19], Calcium hydroxyapatite and calcite precipitates can be found around bacteria in alluvial topsoil. From: Encyclopedia of Biological Chemistry, 2004, Mads Grnborg, Ole Nrregaard Jensen, in Journal of Chromatography Library, 2003. MS also enables the detection of phosphopeptides and phosphoamino acid residues by their diagnostic metastable decomposition via gas phase -elimination of phosphoric acid during time-of-flight mass analysis [3537]. However, it is very unstable in the presence of UVvis irradiation and oxygen. Nucleotide Examples, Function, Bonds & Molecular Structure | What is a Nucleotide in DNA? Recently, a phosphorus centered radical produced by the fragmentation of a P-O bond was identified at low yield (about 0.1% of all radicals) in high LET studies with heavy ion beams [114]. Apparently, negligible changes in bond lengths between C-1 and C-4 and the electronic properties of some atoms can lead to different conformational behaviors, which often play a significant role in the recognition and interaction between substrate and enzyme. To learn more, see our tips on writing great answers. Based on the name of the drug, what is the name of the acid? A DFT investigation Charges of phosphate groups. Fatty acids and their derivatives also function as soaps and detergents. When an electrically charged molecule is combined with mineral phosphorus, it is considered part of the phosphate group. Phosphodiester Bond in DNA & RNA | Linkage, Formation, & Function. Surround a phosphorus atom with four oxygen atoms, and you get a phosphate. Unlike PC and other phospholipids containing glycerol, however, the sphingomyelin backbone is an unsaturated 18-carbon amino-alcohol group called sphingosine. ATP and ADP are often referred to as high-energy phosphates, as are the phosphagens in muscle tissue. The backbone of the DNA is made up of nucleotides which constitute a 5-carbon sugar, a phosphate group, and a nitrogenous base. WebIn a cell, a nucleotide about to be added to the end of a polynucleotide chain will bear a series of three phosphate groups. As cibrail said, DNA is a polymer of nucleotides. A DFT investigation Authors Leonid Gorb 1 , Oleg Shishkin , Jerzy Leszczynski Affiliation Iridoids show a broad spectrum of biological activities, such as antibacterial, antifungal, antiinflammatory, antitumor, hepatoprotective, cardioprotective, antioxidant, and others [110140]. Additionally, membrane lipids are not symmetrically distributed throughout the membrane bilayer, whereby certain phospholipids are more likely to be found in the inner monolayer with the others more likely to be found in the outer leaflet. Common biological targets of antiviral nucleosides are reverse transcriptases or RNA and DNA polymerases. Phosphates induce vascular calcification, and a high concentration of phosphates in blood was found to be a predictor of cardiovascular events. Thus, only [H2PO4] and [HPO4]2 ions are present in significant amounts in the cytosol (62% [H2PO4], 38% [HPO4]2). The best answers are voted up and rise to the top, Not the answer you're looking for? Phosphorus is in group VA so it has 5 valence electrons and Oxygen is in group VIA so each oxygen has 6 valence electrons. Based on the longitudinal dimensions of the vitamin molecules and the observed gallery space, a schematic illustration of the vitamin-LDH structures are shown in Figure 5(b). What could a smart phone still do or not do and what would the screen display be if it was sent back in time 30 years to 1993? We have recently reported the intercalation of folic acid and its derivatives into LDHs for use as a drug stabilization and delivery system.31 Folic acid (N-(4-{[(2-amino-4-oxo-1,4-dihydropteridin-6-yl)methyl]amino}benzoyl)-l-glutamic acid) and its derivative, folinic acid ((S)-2-[4-[(2-amino-5-formyl-4-oxo-5,6,7,8-tetrahydro-1H-pteridin-6-yl)methylamino] benzoyl]aminopentanedioic acid) are used in cancer therapy and in the treatment of vitamin deficiencies. The Distribution and Function of Phosphatidylserine in Cellular Membranes". Next to PC, sphingomyelin (SM) is the most abundant charged lipid, and the most abundant sphingolipid, found in the outer leaflet of cellular membranes. [2] The addition and removal of phosphate groups (phosphorylation and dephosphorylation) are key steps in cell metabolism. This molecule is made up of three phosphate groups and adenosine. It is noteworthy that most of the substituents on the phosphate, such as Etn, l-Arap4N, and GlcpN carry, at neutral pH, a positively charged amino group. Because the amino group has a pKa of about 9.5, it is protonated under physiological pH, making PE a zwitterionic and neutral molecule. In fact, because each base carries a phosphate moiety, the charge-to-mass ratio of nucleic acids is essentially independent of size and form (e.g., single stranded versus double stranded, linear versus plasmid). Cytosine (C) and Thymine (T) are smaller pyrimidines with a single ring structure. Once choline binds to phosphatidic acid, the phosphate group loses one of its negative charges, making PC an overall neutral molecule: a positive charge on the choline and a negative charge on the phosphate. Differences occur in the PO stretching frequency between phosphatidylethanolamine (1227cml) and phosphatidylserine (12201180cm1). The hydrocarbon tails are a major source of energy when each successive two-carbon unit is converted into acetyl-CoA during beta-oxidation, the process of which generates NADH and FADH2 which are subsequently used in the formation of ATP in oxidative phosphorylation. Extraction and isolation methods from plant organisms is well known for a good number of iridoid glycosides. WebThese groups are classified as non-polar and polar based on the atoms composition and arrangements. In accordance with this concept, P. mirabilis mutants lacking l-Arap4N are highly sensitive toward polymyxin B (126). Assignment of acylglycerol bands in infrared spectra. The conjugate base of phosphoric acid that is deprotonated is called a phosphate ion or inorganic phosphate. It was shown that the wave number difference between two stretching modes of carboxylate, as-s=as(COO) s(COO), became larger when it was coordinated to a metal.6466 As described by Yang et al., the value for Na+-IAA, IAA-LDH, and IAA-ZBS were determined to be 161, 162, and 179 cm1, respectively. If free H atoms, which are +1, get added to the O atoms that arent bonded to two things, then the net charge is zero.) "Dynamic Shaping of Cellular Membranes by Phospholipids and Membrane-Deforming Proteins". Gentianales order includes four families called Apocynaceae, Gentianaceae, Loganinaceae, and Rubiaceae (APG III, 2009), highlighting the diversity of the composition of iridoids in these five families. In extracellular fluid (pH = 7.4), this proportion is inverted (61% [HPO4]2, 39% [H2PO4]). in Plant Sciences from University of Hyderabad, India and a Master of Philosophy degree from Annamalai University. Reproduced from Oh, J. M.; Kwak, S. Y.; Choy, J. H. Chapter 1.115, Calcium Phosphates for Cell Transfection. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. Haripriya Munipalli has taught botany and biochemistry to undergraduates for 7 years. Attached to fatty acids, phosphates can make phospholipids. In water solution, orthophosphoric acid and its three derived anions coexist according to the dissociation and recombination equilibria below[3].
