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(19:iso/14:0), in particular, consists of one 17-methylocatdecanoyl chain to the C-1 atom, and one tetradecanoyl 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. 1-17-methylocatdecanoyl-2-myristoyl-sn-glycero-3-phosphoglycerol 1-17-methylocatdecanoyl-2-tetradecanoyl-sn-glycero-3-phospho-(1'-glycerol) 1-17-methylocatdecanoyl-2-tetradecanoyl-sn-glycero-3-phosphoglycerol GPG(19:0/14:0) GPG(33:0) PG(19:0/14:0) PG(33:0) Phosphatidylglycerol(19:0/14:0) Phosphatidylglycerol(33:0) C39H77O10P 736.9964 736.525435196 (2,3-dihydroxypropoxy)({3-[(17-methyloctadecanoyl)oxy]-2-(tetradecanoyloxy)propoxy})phosphinic acid 2,3-dihydroxypropoxy(3-[(17-methyloctadecanoyl)oxy]-2-(tetradecanoyloxy)propoxy)phosphinic acid CCCCCCCCCCCCCC(=O)OC(COC(=O)CCCCCCCCCCCCCCCC(C)C)COP(O)(=O)OCC(O)CO InChI=1S/C39H77O10P/c1-4-5-6-7-8-9-13-18-21-24-27-30-39(43)49-37(34-48-50(44,45)47-32-36(41)31-40)33-46-38(42)29-26-23-20-17-15-12-10-11-14-16-19-22-25-28-35(2)3/h35-37,40-41H,4-34H2,1-3H3,(H,44,45) JQVNVWCDQCLZIY-UHFFFAOYSA-N Solid Membrane logp 7.79 ALOGPS logs -6.77 ALOGPS solubility 1.24e-04 g/l ALOGPS logp 11.22 ChemAxon pka_strongest_acidic 1.89 ChemAxon pka_strongest_basic -3 ChemAxon iupac (2,3-dihydroxypropoxy)({3-[(17-methyloctadecanoyl)oxy]-2-(tetradecanoyloxy)propoxy})phosphinic acid ChemAxon average_mass 736.9964 ChemAxon mono_mass 736.525435196 ChemAxon smiles CCCCCCCCCCCCCC(=O)OC(COC(=O)CCCCCCCCCCCCCCCC(C)C)COP(O)(=O)OCC(O)CO ChemAxon formula C39H77O10P ChemAxon inchi InChI=1S/C39H77O10P/c1-4-5-6-7-8-9-13-18-21-24-27-30-39(43)49-37(34-48-50(44,45)47-32-36(41)31-40)33-46-38(42)29-26-23-20-17-15-12-10-11-14-16-19-22-25-28-35(2)3/h35-37,40-41H,4-34H2,1-3H3,(H,44,45) ChemAxon inchikey JQVNVWCDQCLZIY-UHFFFAOYSA-N ChemAxon polar_surface_area 148.82 ChemAxon refractivity 199.86 ChemAxon polarizability 90.24 ChemAxon rotatable_bond_count 40 ChemAxon acceptor_count 6 ChemAxon donor_count 3 ChemAxon physiological_charge -1 ChemAxon formal_charge 0 ChemAxon Glycerophospholipid metabolism ec00564 phospholipid biosynthesis (CL(19:iso/14:0/14:0/14:0)) 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.
