It is a glycerophospholipid containing a diacylglycerol, with a cytidine diphosphate attached to the oxygen O1 or O2 of the glycerol part. As is the case with diacylglycerols, phosphatidylserines can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. CDP-DG(15:0/15:0), in particular, consists of two pentadecanoyl chain at positions C-1 and C2. In E. coli glycerophospholipid metabolism, The biosynthesis of CDP-diacylglycerol (CDP-DG) involves condensation of phosphatidic acid (PA) and cytidine triphosphate, with elimination of pyrophosphate, catalysed by the enzyme CDP-diacylglycerol synthase. The resulting CDP-diacylglycerol can be utilized immediately for the synthesis of phosphatidylglycerol (PG), and thence cardiolipin (CL), and of phosphatidylinositol (PI). CDP-DG(15:0/15:0) is also a substrate of CDP-diacylglycerol pyrophosphatase. It is involved in CDP-diacylglycerol degradation pathway. 1,2-dipentadecanoyl-rac-glycero-3-CDP 1,2-dipentadecanoyl-rac-glycero-3-cytidine-5'-diphosphate 1,2-dipentadecanoyl-rac-glycero-3-cytidine-5'-diphosphate 1,2-Dipentadecanoyl-rac-glycero-3-cytidine-5'-diphosphoric acid CDP-DG(30:0) CDP-Diacylglycerol(15:0/15:0) CDP-Diacylglycerol(30:0) C42H77N3O15P2 926.032 925.482992787 {[(2R,3R,5R)-5-(4-amino-2-oxo-1,2-dihydropyrimidin-1-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}({[(2R)-2,3-bis(pentadecanoyloxy)propoxy](hydroxy)phosphoryl}oxy)phosphinic acid [(2R,3R,5R)-5-(4-amino-2-oxopyrimidin-1-yl)-3,4-dihydroxyoxolan-2-yl]methoxy([(2R)-2,3-bis(pentadecanoyloxy)propoxy(hydroxy)phosphoryl]oxy)phosphinic acid [H][C@@](COC(=O)CCCCCCCCCCCCCC)(COP(O)(=O)OP(O)(=O)OC[C@H]1O[C@H](C(O)[C@H]1O)N1C=CC(N)=NC1=O)OC(=O)CCCCCCCCCCCCCC InChI=1S/C42H77N3O15P2/c1-3-5-7-9-11-13-15-17-19-21-23-25-27-37(46)55-31-34(58-38(47)28-26-24-22-20-18-16-14-12-10-8-6-4-2)32-56-61(51,52)60-62(53,54)57-33-35-39(48)40(49)41(59-35)45-30-29-36(43)44-42(45)50/h29-30,34-35,39-41,48-49H,3-28,31-33H2,1-2H3,(H,51,52)(H,53,54)(H2,43,44,50)/t34-,35-,39+,40?,41-/m1/s1 FRQHMAQSRZOPBJ-ZOGSNCAGSA-N Solid Membrane logp 5.43 ALOGPS logs -4.95 ALOGPS solubility 1.04e-02 g/l ALOGPS logp 8.67 ChemAxon pka_strongest_acidic 1.86 ChemAxon pka_strongest_basic -0.032 ChemAxon iupac {[(2R,3R,5R)-5-(4-amino-2-oxo-1,2-dihydropyrimidin-1-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}({[(2R)-2,3-bis(pentadecanoyloxy)propoxy](hydroxy)phosphoryl}oxy)phosphinic acid ChemAxon average_mass 926.032 ChemAxon mono_mass 925.482992787 ChemAxon smiles [H][C@@](COC(=O)CCCCCCCCCCCCCC)(COP(O)(=O)OP(O)(=O)OC[C@H]1O[C@H](C(O)[C@H]1O)N1C=CC(N)=NC1=O)OC(=O)CCCCCCCCCCCCCC ChemAxon formula C42H77N3O15P2 ChemAxon inchi InChI=1S/C42H77N3O15P2/c1-3-5-7-9-11-13-15-17-19-21-23-25-27-37(46)55-31-34(58-38(47)28-26-24-22-20-18-16-14-12-10-8-6-4-2)32-56-61(51,52)60-62(53,54)57-33-35-39(48)40(49)41(59-35)45-30-29-36(43)44-42(45)50/h29-30,34-35,39-41,48-49H,3-28,31-33H2,1-2H3,(H,51,52)(H,53,54)(H2,43,44,50)/t34-,35-,39+,40?,41-/m1/s1 ChemAxon inchikey FRQHMAQSRZOPBJ-ZOGSNCAGSA-N ChemAxon polar_surface_area 263.27 ChemAxon refractivity 231.01 ChemAxon polarizability 100.51 ChemAxon rotatable_bond_count 40 ChemAxon acceptor_count 12 ChemAxon donor_count 5 ChemAxon physiological_charge -2 ChemAxon formal_charge 0 ChemAxon Glycerophospholipid metabolism ec00564 phospholipid biosynthesis CDP-DG(15:0/15:0) 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 PS (16:1(9z)/18:1(11z))L-1-phosphatidylserine or a L-1-phosphatidy PE(16:1(9z)/18:1(11z)) (phosphatidylethanolamine) through a phosphatidylserine decarboxylase, on the other hand PGP(16:1(9z)/18:1(11z)) L-1-phosphatidylglycerol-phosphate gets transformed into a PG(16:1(9z)/18:1(11z)) 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.
