| Description | PGP(18:1(9Z)/16:1(9Z)), also known as PGP(18:1/16:1) Or PGP(34:2), 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. 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. PGP(18:1(9Z)/16:1(9Z)) is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, PGP(18:1(9Z)/16:1(9Z)) participates in a number of enzymatic reactions. In particular, PGP(18:1(9Z)/16:1(9Z)) and cytidine monophosphate can be biosynthesized from CDP-DG(18:1(9Z)/16:1(9Z)) and glycerol 3-phosphate through its interaction with the enzyme CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase, mitochondrial. In addition, PGP(18:1(9Z)/16:1(9Z)) can be converted into PG(18:1(9Z)/16:1(9Z)); which is catalyzed by the enzyme phosphatidylglycerophosphatase and protein-tyrosine phosphatase 1. Bioynthesis proceeds by condensation of phosphatidic acid and cytidine triphosphate with elimination of pyrophosphate via the action of phosphatidate cytidyltransferase (or CDP-synthase). 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. In humans, PGP(18:1(9Z)/16:1(9Z)) is involved in cardiolipin biosynthesis. PGP(18:1(9Z)/16:1(9Z)), in particular, consists of one chain of oleic acid at the C-1 position and one chain of palmitoleic acid at the C-2 position. It is well established that the concentration of Phosphatidylglycerolphosphate increases during fetal development. PGP(18:1(9Z)/16:1(9Z)) is a phosphatidylglycerolphosphate or glycerophospholipid (PGP or GP). PGP also serves as a precursor for the synthesis of cardiolipin. 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). |
