Description | PGP(16:0/20:4(5Z,8Z,11Z,14Z)), also known as PGP(16:0/20:4) Or PGP(36:4), 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. 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. Phosphatidylglycerol is formed from phosphatidic acid by a sequence of enzymatic reactions that proceeds via the intermediate, cytidine diphosphate diacylglycerol (CDP-diacylglycerol). It is a glycerophospholipid in which a phosphoglycerol moiety occupies a glycerol substitution site followed by another phosphate moiety. PGP(16:0/20:4(5Z,8Z,11Z,14Z)) is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, PGP(16:0/20:4(5Z,8Z,11Z,14Z)) participates in a number of enzymatic reactions. In particular, PGP(16:0/20:4(5Z,8Z,11Z,14Z)) and cytidine monophosphate can be biosynthesized from CDP-DG(16:0/20:4(5Z,8Z,11Z,14Z)) and glycerol 3-phosphate through the action of the enzyme CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase, mitochondrial. In addition, PGP(16:0/20:4(5Z,8Z,11Z,14Z)) can be converted into PG(16:0/20:4(5Z,8Z,11Z,14Z)); which is mediated by the enzyme phosphatidylglycerophosphatase and protein-tyrosine phosphatase 1. Phosphatidylglycerolphosphate is present at a level of 1-2% in most animal tissues, but it can be the second most abundant phospholipid in lung surfactant at up to 11% of the total. In humans, PGP(16:0/20:4(5Z,8Z,11Z,14Z)) is involved in cardiolipin biosynthesis. |
