Phosphatidylglycerols consist of a glycerol 3-phosphate backbone esterified to either saturated or unsaturated fatty acids on carbons 1 and 2. As is the case with diacylglycerols, phosphatidylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PG(14:0(3-OH)/10:0(3-OH)), in particular, consists of one 3-hydroxytetradecanoyl chain to the C-1 atom, and one 3-hydroxydecanoyl to the C-2 atom. In E. coli glycerophospholipid metabolism, phosphatidylglycerol is formed from phosphatidic acid (1,2-diacyl-sn-glycerol 3-phosphate) by a sequence of enzymatic reactions that proceeds via two intermediates, cytidine diphosphate diacylglycerol (CDP-diacylglycerol) and phosphatidylglycerophosphate (PGP, a phosphorylated phosphatidylglycerol). Phosphatidylglycerols, along with CDP-diacylglycerol, also serve as precursor molecules for the synthesis of cardiolipin, a phospholipid found in membranes. 1-3-hydroxytetradecanoyl-2-3-hydroxydecanoyl-sn-glycero-3-phospho-(1'-glycerol) 1-3-hydroxytetradecanoyl-2-3-hydroxydecanoyl-sn-glycero-3-phosphoglycerol 1-3-hydroxytetradecanoyl-2-NULL-sn-glycero-3-phospho-(1'-glycerol) 1-3-hydroxytetradecanoyl-2-NULL-sn-glycero-3-phosphoglycerol GPG(14:0/10:0) GPG(24:0) PG(14:0/10:0) PG(24:0) Phosphatidylglycerol(14:0/10:0) Phosphatidylglycerol(24:0) C30H59O12P 642.764 642.374414338 [(2S)-2,3-dihydroxypropoxy][(2R)-3-[(3-hydroxydecanoyl)oxy]-2-[(3-hydroxytetradecanoyl)oxy]propoxy]phosphinic acid (2S)-2,3-dihydroxypropoxy((2R)-3-[(3-hydroxydecanoyl)oxy]-2-[(3-hydroxytetradecanoyl)oxy]propoxy)phosphinic acid [H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CC(O)CCCCCCC)OC(=O)CC(O)CCCCCCCCCCC InChI=1S/C30H59O12P/c1-3-5-7-9-10-11-12-14-16-18-26(33)20-30(36)42-28(24-41-43(37,38)40-22-27(34)21-31)23-39-29(35)19-25(32)17-15-13-8-6-4-2/h25-28,31-34H,3-24H2,1-2H3,(H,37,38)/t25?,26?,27-,28+/m0/s1 WEYGZADQRIFOSJ-LWCGHFMUSA-N Solid Membrane logp 3.50 ALOGPS logs -5.50 ALOGPS solubility 2.05e-03 g/l ALOGPS logp 4.92 ChemAxon pka_strongest_acidic 1.89 ChemAxon pka_strongest_basic -2.8 ChemAxon iupac [(2S)-2,3-dihydroxypropoxy][(2R)-3-[(3-hydroxydecanoyl)oxy]-2-[(3-hydroxytetradecanoyl)oxy]propoxy]phosphinic acid ChemAxon average_mass 642.764 ChemAxon mono_mass 642.374414338 ChemAxon smiles [H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CC(O)CCCCCCC)OC(=O)CC(O)CCCCCCCCCCC ChemAxon formula C30H59O12P ChemAxon inchi InChI=1S/C30H59O12P/c1-3-5-7-9-10-11-12-14-16-18-26(33)20-30(36)42-28(24-41-43(37,38)40-22-27(34)21-31)23-39-29(35)19-25(32)17-15-13-8-6-4-2/h25-28,31-34H,3-24H2,1-2H3,(H,37,38)/t25?,26?,27-,28+/m0/s1 ChemAxon inchikey WEYGZADQRIFOSJ-LWCGHFMUSA-N ChemAxon polar_surface_area 189.28 ChemAxon refractivity 161.53 ChemAxon polarizability 71.88 ChemAxon rotatable_bond_count 32 ChemAxon acceptor_count 8 ChemAxon donor_count 5 ChemAxon physiological_charge -1 ChemAxon formal_charge 0 ChemAxon Glycerophospholipid metabolism ec00564 phospholipid biosynthesis (CL(17:0cycw7c/10:0(3-OH)/14:0/14:0)) Phospholipids are membrane components in E. coli. The major phospholipids of E. coli are phosphatidylethanolamine, phosphatidylglycerol and cardiolipin. All phospholipids contain sn-glycerol-3-phosphate esterified with fatty acids at the sn-1 and sn-2 positions. The reaction starts from a glycerone phosphate (dihydroxyacetone phosphate) produced in glycolysis. The glycerone phosphate is transformed to a sn-glycerol 3-phosphate (glycerol 3 phosphate) by NADPH driven glycerol-3-phosphate dehydrogenase. Sn-glycerol 3-phosphate is transformed to a 1-acyl-sn-glycerol 3-phosphate(1-oleyl-2-lyso-phosphatidate , 1-palmitoylglycerol 3-phosphate , 1-stearoyl-sn-glycerol 3-phosphate). This can be achieve by a sn-glycerol-3-phosphate 1-0-acyltransferase that interacts either with a long-chain acyl-CoA or with an acyl-[acp]. The 1-acyl-sn-glycerol 3-phosphate is transformed into a 1,2-diacyl-sn-glycerol 3-phosphate through a 1-acylglycerol-3-phosphate O-acyltransferase. This compound is then converted into a CPD-diacylglycerol through a CTP (phosphatidate cytididyltransferase. CPD-diacylglycerol can be transformed either to a L-1-phosphatidylserine or a L-1-phosphatidylglycerol-phosphate through a phosphatidylserine synthase or a phosphatidylglycerophosphate synthase respectively. The L-1-phosphatidylserine transforms into L-1-phosphatidylethanolamine through a phosphatidylserine decarboxylase, o the other hand L-1-phosphatidylglycerol-phosphate gets transformed into a L-1-phosphatidyl-glycerol through a phosphatidylglycerophosphatase. These 2 products combines produce a cardiolipin and a ethanolamine. The L-1 phosphatidyl-glycerol can also interact with cardiolipin synthase resulting in a glycerol and a cardiolipin.
