These are glycerolipids lipids containing a common glycerol backbone to which at least one fatty acyl group is esterified. DG(16:0/19:1(9Z)/0:0) is also a substrate of diacylglycerol kinase. It is involved in the phospholipid metabolic pathway. 1-hexadecanoyl-2-(9Z-nonadecenoyl)-sn-glycerol 1-palmitoyl-2-9Z-nonadecenoyl-sn-glycerol DAG(16:0/19:1) DAG(35:1) DG(16:0/19:1) DG(35:1) Diacylglycerol Diacylglycerol(16:0/19:1) Diacylglycerol(35:1) Diglyceride C38H72O5 608.989 608.537975418 (2S)-3-(hexadecanoyloxy)-2-hydroxypropyl (9Z)-nonadec-9-enoate (2S)-3-(hexadecanoyloxy)-2-hydroxypropyl (9Z)-nonadec-9-enoate [H][C@](O)(COC(=O)CCCCCCCCCCCCCCC)COC(=O)CCCCCCC\C=C/CCCCCCCCC InChI=1S/C38H72O5/c1-3-5-7-9-11-13-15-17-18-19-21-23-25-27-29-31-33-38(41)43-35-36(39)34-42-37(40)32-30-28-26-24-22-20-16-14-12-10-8-6-4-2/h18-19,36,39H,3-17,20-35H2,1-2H3/b19-18-/t36-/m0/s1 VALKELPGSMJADF-QAHLDSHBSA-N Membrane logp 10.25 ALOGPS logs -7.57 ALOGPS solubility 1.64e-05 g/l ALOGPS logp 12.97 ChemAxon pka_strongest_acidic 13.63 ChemAxon pka_strongest_basic -3.4 ChemAxon iupac (2S)-3-(hexadecanoyloxy)-2-hydroxypropyl (9Z)-nonadec-9-enoate ChemAxon average_mass 608.989 ChemAxon mono_mass 608.537975418 ChemAxon smiles [H][C@](O)(COC(=O)CCCCCCCCCCCCCCC)COC(=O)CCCCCCC\C=C/CCCCCCCCC ChemAxon formula C38H72O5 ChemAxon inchi InChI=1S/C38H72O5/c1-3-5-7-9-11-13-15-17-18-19-21-23-25-27-29-31-33-38(41)43-35-36(39)34-42-37(40)32-30-28-26-24-22-20-16-14-12-10-8-6-4-2/h18-19,36,39H,3-17,20-35H2,1-2H3/b19-18-/t36-/m0/s1 ChemAxon inchikey VALKELPGSMJADF-QAHLDSHBSA-N ChemAxon polar_surface_area 72.83 ChemAxon refractivity 182.62 ChemAxon polarizability 80.72 ChemAxon rotatable_bond_count 36 ChemAxon acceptor_count 3 ChemAxon donor_count 1 ChemAxon physiological_charge 0 ChemAxon formal_charge 0 ChemAxon phospholipid biosynthesis (PE(16:0/19:iso)) 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.
