Common NameCDP-DG(16:0/i-19:0)
DescriptionCDP-DG(16:0/i-19:0) is a cytidine diphosphate diacylglycerol or CDP-diacylglycerol. It is a glycerophospholipid in which a cytidine diphosphate moiety occupies a glycerol substitution site. As is the case with diacylglycerols, CDP-diacylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. CDP-DG(16:0/i-19:0), in particular, consists of one hexadecanoyl chain at the C-1 position and one 17-methyloctadecanoyl chain at the C-2 position. In E. coli glycerophospholipid metabolism, the biosynthesis of CDP-diacylglycerol (CDP-DG) involves condensation of phosphatidic acid (PA) and cytidine triphosphate, with elimination of pyrophosphate, catalysed by the enzyme CDP-diacylglycerol synthase. The resulting CDP-diacylglycerol can be utilized immediately for the synthesis of phosphatidylglycerol (PG), and thence cardiolipin (CL), and of phosphatidylinositol (PI). CDP-DG(16:0/i-19:0) is also a substrate of CDP-diacylglycerol pyrophosphatase. It is involved in CDP-diacylglycerol degradation pathway.
