Description | PGP(18:3(6Z,9Z,12Z)/22:4(7Z,10Z,13Z,16Z)), also known as PGP(18:3/22:4) Or PGP(40:7), Belongs to the class of organic compounds known as phosphatidylglycerophosphates. These are glycerophosphoglycerophosphates in which two fatty acids are bonded to the 1-glycerol moiety through ester linkages. PGPs have a net charge of -1 at physiological pH and are found in high concentration in mitochondrial membranes and as components of pulmonary surfactant. PGP also serves as a precursor for the synthesis of cardiolipin. PGP(18:3(6Z,9Z,12Z)/22:4(7Z,10Z,13Z,16Z)) is a phosphatidylglycerolphosphate or glycerophospholipid (PGP or GP). CDP-diacylglycerol then reacts with glycerol-3-phosphate via phosphatidylglycerophosphate synthase to form 3-sn-phosphatidyl-1'-sn-glycerol 3'-phosphoric acid, with the release of cytidine monophosphate (CMP). PGP(18:3(6Z,9Z,12Z)/22:4(7Z,10Z,13Z,16Z)) is an extremely weak basic (essentially neutral) compound (based on its pKa). It is well established that the concentration of Phosphatidylglycerolphosphate increases during fetal development. Bioynthesis proceeds by condensation of phosphatidic acid and cytidine triphosphate with elimination of pyrophosphate via the action of phosphatidate cytidyltransferase (or CDP-synthase). As is the case with diacylglycerols, phosphatidylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Phosphatidylglycerolphosphate may be present in animal tissues merely as a precursor for diphosphatidylglycerol (cardiolipin). |
