It is a glycerophospholipid in which a phosphorylethanolamine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphoethanolamines can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PE(14:0/14:0), in particular, consists of two tetradecanoyl chains at positions C-1 and C-2. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PEs are neutral zwitterions at physiological pH. They mostly have palmitic or stearic acid on carbon 1 and a long chain unsaturated fatty acid (e.g. 18:2, 20:4 and 22:6) on carbon 2. PE synthesis can occur via two pathways. The first requires that ethanolamine be activated by phosphorylation and then coupled to CDP. The ethanolamine is then transferred from CDP-ethanolamine to phosphatidic acid to yield PE. The second involves the decarboxylation of PS. 1,2-Dimyristoyl-rac-glycero-3-phosphoethanolamine 1,2-ditetradecanoyl-rac-glycero-3-phosphoethanolamine 1-phosphatidylethanolamine O-(1-β-acyl-2-acyl-sn-glycero-3-phospho)-ethanolamine A 1-phosphatidylethanolamine A phosphatidylethenolamine An L-1-phosphotidylethanolamine Glycerophosphoethanolamine GPEtn(14:0/14:0) GPEtn(28:0) L-1-phosphotidylethanolamine O-(1-β-acyl-2-acyl-sn-glycero-3-phospho)-ethanolamine PE(14:0/14:0) PE(28:0) Phophatidylethanolamine(14:0/14:0) Phophatidylethanolamine(28:0) Phosphatidylethanolamine Phosphatidylethanolamine (ecoli) PtdEtn C33H66NO8P 635.8528 635.452604605 (2-aminoethoxy)[(2R)-2,3-bis(tetradecanoyloxy)propoxy]phosphinic acid 2-aminoethoxy((2R)-2,3-bis(tetradecanoyloxy)propoxy)phosphinic acid [H][C@@](COC(=O)CCCCCCCCCCCCC)(COP(O)(=O)OCCN)OC(=O)CCCCCCCCCCCCC InChI=1S/C33H66NO8P/c1-3-5-7-9-11-13-15-17-19-21-23-25-32(35)39-29-31(30-41-43(37,38)40-28-27-34)42-33(36)26-24-22-20-18-16-14-12-10-8-6-4-2/h31H,3-30,34H2,1-2H3,(H,37,38)/t31-/m1/s1 NEZDNQCXEZDCBI-WJOKGBTCSA-N Solid Inner membrane Membrane Outer membrane logp 7.06 ALOGPS logs -6.49 ALOGPS solubility 2.05e-04 g/l ALOGPS logp 8.67 ChemAxon pka_strongest_acidic 1.87 ChemAxon pka_strongest_basic 10 ChemAxon iupac (2-aminoethoxy)[(2R)-2,3-bis(tetradecanoyloxy)propoxy]phosphinic acid ChemAxon average_mass 635.8528 ChemAxon mono_mass 635.452604605 ChemAxon smiles [H][C@@](COC(=O)CCCCCCCCCCCCC)(COP(O)(=O)OCCN)OC(=O)CCCCCCCCCCCCC ChemAxon formula C33H66NO8P ChemAxon inchi InChI=1S/C33H66NO8P/c1-3-5-7-9-11-13-15-17-19-21-23-25-32(35)39-29-31(30-41-43(37,38)40-28-27-34)42-33(36)26-24-22-20-18-16-14-12-10-8-6-4-2/h31H,3-30,34H2,1-2H3,(H,37,38)/t31-/m1/s1 ChemAxon inchikey NEZDNQCXEZDCBI-WJOKGBTCSA-N ChemAxon polar_surface_area 134.38 ChemAxon refractivity 172.6 ChemAxon polarizability 76.48 ChemAxon rotatable_bond_count 35 ChemAxon acceptor_count 5 ChemAxon donor_count 2 ChemAxon physiological_charge 0 ChemAxon formal_charge 0 ChemAxon Glycerophospholipid metabolism ec00564 Metabolic pathways eco01100 phospholipid biosynthesis (CL(18:1(9Z)/14:0/14:0/18:1(9Z))) Phospholipids are membrane components in E. coli.

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. PW001986 Metabolic phospholipid biosynthesis (CL(19:iso/14:0(3-OH)/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.
