Common Name | PGP(16:0/20:3(5Z,8Z,11Z)) |

Description | PGP(16:0/20:3(5Z,8Z,11Z)), also known as PGP(16:0/20:3) Or PGP(36:3), 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. 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. It is a glycerophospholipid in which a phosphoglycerol moiety occupies a glycerol substitution site followed by another phosphate moiety. PGP(16:0/20:3(5Z,8Z,11Z)) is an extremely weak basic (essentially neutral) compound (based on its pKa). 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. 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. |
