Note

CDP-DG(a-21:0/a-21:0) 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(a-21:0/a-21:0), in particular, consists of one chain of anteisoheneicosanoic acid at the C-1 position and one chain of anteisoheneicosanoic 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).
