CDP-DG(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/20:2(11Z,14Z))
CDP-DG(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/20:2(11Z,14Z)) is a cytidine diphosphate diacylglycerol or CDP-diacylglycerol (CDP-DG). CDP-diacylglycerol is an important branchpoint intermediate in eukaryotic phospholipid biosynthesis and could be a key regulatory molecule in phospholipid metabolism. 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. Fatty acids containing 16, 18 and 20 carbons are the most common. CDP-DG(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/20:2(11Z,14Z)), in particular, consists of one chain of docosahexaenoic acid at the C-1 position and one chain of eicosadienoic acid at the C-2 position. Cytidine diphosphate diacylglycerols are rarely noticed in analyses of lipid compositions of tissues, as they are present is such small amounts (perhaps only 0.05\\% or so of the total phospholipids).
