Common NamePG(24:0/24:0)
DescriptionPG(24:0/24:0) 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(24:0/24:0), in particular, consists of two tetracosanoyl chains at positions C-1 and C-2. 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.
