PG(18:1(9Z)/22:4(7Z,10Z,13Z,16Z))
IUPAC 名称
[(2S)-2,3-dihydroxypropoxy][(2R)-2-(docosa-7,10,13,16-tetraenoyloxy)-3-(octadec-9-enoyloxy)propoxy]phosphinic acid
描述
PG(18:1(9Z)/22:4(7Z,10Z,13Z,16Z)) 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(18:1(9Z)/22:4(7Z,10Z,13Z,16Z)), in particular, consists of one 9Z-octadecenoyl chain to the C-1 atom, and one 7Z,10Z,13Z,16Z-docosatetraenoyl 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.
