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(18:1(9Z)/12:0(3-OH)), in particular, consists of one 9Z-octadecenoyl chain to the C-1 atom, and one 3-hydroxydodecanoyl 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-(9Z-octadecenoyl)-2-3-hydroxydodecanoyl-sn-glycero-3-phospho-(1'-glycerol) 1-(9Z-octadecenoyl)-2-3-hydroxydodecanoyl-sn-glycero-3-phosphoglycerol 1-oleoyl-2-3-hydroxydodecanoyl-sn-glycero-3-phosphoglycerol GPG(18:1/12:0) GPG(30:1) PG(18:1/12:0) PG(30:1) Phosphatidylglycerol(18:1/12:0) Phosphatidylglycerol(30:1) C36H69O11P 708.911 708.45775004 [(2S)-2,3-dihydroxypropoxy][(2R)-3-[(3-hydroxydodecanoyl)oxy]-2-[(9Z)-octadec-9-enoyloxy]propoxy]phosphinic acid (2S)-2,3-dihydroxypropoxy((2R)-3-[(3-hydroxydodecanoyl)oxy]-2-[(9Z)-octadec-9-enoyloxy]propoxy)phosphinic acid [H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CC(O)CCCCCCCCC)OC(=O)CCCCCCC\C=C/CCCCCCCC InChI=1S/C36H69O11P/c1-3-5-7-9-11-12-13-14-15-16-17-18-20-22-24-26-35(40)47-34(31-46-48(42,43)45-29-33(39)28-37)30-44-36(41)27-32(38)25-23-21-19-10-8-6-4-2/h14-15,32-34,37-39H,3-13,16-31H2,1-2H3,(H,42,43)/b15-14-/t32?,33-,34+/m0/s1 HQQVCBSYTVFDBJ-IQAYTRFVSA-N Solid Membrane logp 6.29 ALOGPS logs -6.30 ALOGPS solubility 3.59e-04 g/l ALOGPS logp 8.46 ChemAxon pka_strongest_acidic 1.89 ChemAxon pka_strongest_basic -2.8 ChemAxon iupac [(2S)-2,3-dihydroxypropoxy][(2R)-3-[(3-hydroxydodecanoyl)oxy]-2-[(9Z)-octadec-9-enoyloxy]propoxy]phosphinic acid ChemAxon average_mass 708.911 ChemAxon mono_mass 708.45775004 ChemAxon smiles [H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CC(O)CCCCCCCCC)OC(=O)CCCCCCC\C=C/CCCCCCCC ChemAxon formula C36H69O11P ChemAxon inchi InChI=1S/C36H69O11P/c1-3-5-7-9-11-12-13-14-15-16-17-18-20-22-24-26-35(40)47-34(31-46-48(42,43)45-29-33(39)28-37)30-44-36(41)27-32(38)25-23-21-19-10-8-6-4-2/h14-15,32-34,37-39H,3-13,16-31H2,1-2H3,(H,42,43)/b15-14-/t32?,33-,34+/m0/s1 ChemAxon inchikey HQQVCBSYTVFDBJ-IQAYTRFVSA-N ChemAxon polar_surface_area 169.05 ChemAxon refractivity 188.74 ChemAxon polarizability 82.91 ChemAxon rotatable_bond_count 37 ChemAxon acceptor_count 7 ChemAxon donor_count 4 ChemAxon physiological_charge -1 ChemAxon formal_charge 0 ChemAxon Glycerophospholipid metabolism ec00564 phospholipid biosynthesis (CL(18:1(9Z)/12:0(3-OH)/18:1(9Z)/12:0(3-OH))) 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.
