| Description | PGP(18:2(9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)), also known as PGP(18:2/22:5) 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. It is a glycerophospholipid in which a phosphoglycerol moiety occupies a glycerol substitution site followed by another phosphate moiety. PGP(18:2(9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)) is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, PGP(18:2(9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)) participates in a number of enzymatic reactions. In particular, PGP(18:2(9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)) and cytidine monophosphate can be biosynthesized from CDP-DG(18:2(9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)) and glycerol 3-phosphate; which is catalyzed by the enzyme CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase, mitochondrial. In addition, PGP(18:2(9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)) can be converted into PG(18:2(9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)) through the action of the enzyme phosphatidylglycerophosphatase and protein-tyrosine phosphatase 1. In humans, PGP(18:2(9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)) is involved in cardiolipin biosynthesis. Finally, phosphatidylglycerol is formed by the action of specific phosphatases. 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. 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. |
