Name: | PG(15:0/19:iso) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Description | PG(15:0/19:iso) is a phosphatidylglycerol. Phosphatidylglycerols consist of a glycerol 3-phosphate backbone esterified to either saturated or unsaturated fatty acids on carbons 1 and 2. As is the case with diacylglycerols, phosphatidylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PG(15:0/19:iso), in particular, consists of one pentadecanoyl chain to the C-1 atom, and one 17-methylocatdecanoyl to the C-2 atom. In E. coli glycerophospholipid metabolism, phosphatidylglycerol is formed from phosphatidic acid (1,2-diacyl-sn-glycerol 3-phosphate) by a sequence of enzymatic reactions that proceeds via two intermediates, cytidine diphosphate diacylglycerol (CDP-diacylglycerol) and phosphatidylglycerophosphate (PGP, a phosphorylated phosphatidylglycerol). Phosphatidylglycerols, along with CDP-diacylglycerol, also serve as precursor molecules for the synthesis of cardiolipin, a phospholipid found in membranes. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Chemical Taxonomy | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Description | belongs to the class of organic compounds known as phosphatidylglycerols. These are glycerophosphoglycerols 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 to the C-1 and C-2 positions. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
