| Common Name | PGP(18:0/20:3(5Z,8Z,11Z)) |

| Description | PGP(18:0/20:3(5Z,8Z,11Z)), also known as PGP(18:0/20:3) Or PGP(38:3), 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. PGP(18:0/20:3(5Z,8Z,11Z)) is an extremely weak basic (essentially neutral) compound (based on its pKa). 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. 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. Finally, phosphatidylglycerol is formed by the action of specific phosphatases. PGP(18:0/20:3(5Z,8Z,11Z)) is a phosphatidylglycerolphosphate or glycerophospholipid (PGP or GP). |
