Identification
Name:PG(14:0(3-OH)/12:0(3-OH))
DescriptionPG(14:0(3-OH)/12:0(3-OH)) 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(14:0(3-OH)/12:0(3-OH)), in particular, consists of one 3-hydroxytetradecanoyl chain to the C-1 atom, and one 3-hydroxydodecanoyl 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.
