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(16:0/19:iso), in particular, consists of one hexadecanoyl chain to the C-1 atom, and one 17-methylocatdecanoyl 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-hexadecanoyl-2-17-methylocatdecanoyl-sn-glycero-3-phospho-(1'-glycerol) 1-hexadecanoyl-2-17-methylocatdecanoyl-sn-glycero-3-phosphoglycerol 1-palmitoyl-2-17-methylocatdecanoyl-sn-glycero-3-phosphoglycerol GPG(16:0/19:0) GPG(35:0) PG(16:0/19:0) PG(35:0) Phosphatidylglycerol(16:0/19:0) Phosphatidylglycerol(35:0) C41H81O10P 765.0496 764.556735324 (2,3-dihydroxypropoxy)[3-(hexadecanoyloxy)-2-[(17-methyloctadecanoyl)oxy]propoxy]phosphinic acid 2,3-dihydroxypropoxy(3-(hexadecanoyloxy)-2-[(17-methyloctadecanoyl)oxy]propoxy)phosphinic acid CCCCCCCCCCCCCCCC(=O)OCC(COP(O)(=O)OCC(O)CO)OC(=O)CCCCCCCCCCCCCCCC(C)C InChI=1S/C41H81O10P/c1-4-5-6-7-8-9-10-12-16-19-22-25-28-31-40(44)48-35-39(36-50-52(46,47)49-34-38(43)33-42)51-41(45)32-29-26-23-20-17-14-11-13-15-18-21-24-27-30-37(2)3/h37-39,42-43H,4-36H2,1-3H3,(H,46,47) DKYYKBFTJDCTBP-UHFFFAOYSA-N Solid Membrane logp 8.19 ALOGPS logs -6.89 ALOGPS solubility 9.97e-05 g/l ALOGPS logp 12.11 ChemAxon pka_strongest_acidic 1.89 ChemAxon pka_strongest_basic -3 ChemAxon iupac (2,3-dihydroxypropoxy)[3-(hexadecanoyloxy)-2-[(17-methyloctadecanoyl)oxy]propoxy]phosphinic acid ChemAxon average_mass 765.0496 ChemAxon mono_mass 764.556735324 ChemAxon smiles CCCCCCCCCCCCCCCC(=O)OCC(COP(O)(=O)OCC(O)CO)OC(=O)CCCCCCCCCCCCCCCC(C)C ChemAxon formula C41H81O10P ChemAxon inchi InChI=1S/C41H81O10P/c1-4-5-6-7-8-9-10-12-16-19-22-25-28-31-40(44)48-35-39(36-50-52(46,47)49-34-38(43)33-42)51-41(45)32-29-26-23-20-17-14-11-13-15-18-21-24-27-30-37(2)3/h37-39,42-43H,4-36H2,1-3H3,(H,46,47) ChemAxon inchikey DKYYKBFTJDCTBP-UHFFFAOYSA-N ChemAxon polar_surface_area 148.82 ChemAxon refractivity 209.06 ChemAxon polarizability 94.51 ChemAxon rotatable_bond_count 42 ChemAxon acceptor_count 6 ChemAxon donor_count 3 ChemAxon physiological_charge -1 ChemAxon formal_charge 0 ChemAxon Glycerophospholipid metabolism ec00564 phospholipid biosynthesis (CL(18:1(9Z)/16:0/16:0/19:0cycv8c) 2) 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.
