Metabolite Identification
Common NameCDP-ethanolamine
DescriptionCDP-ethanolamine, also known as cytidine 5’-diphosphoethanolamine, belongs to the class of organic compounds known as CDP-ethanolamines. These are phosphoethanolamines that consist of an ethanolamine having a cytidine 5'-diphosphate moiety attached to the oxygen. CDP-ethanolamine is a very strong basic compound (based on its pKa). In humans, CDP-ethanolamine is involved in phosphatidylethanolamine biosynthesis. Outside of the human body, CDP-ethanolamine has been detected, but not quantified in, several different foods, such as Chinese water chestnuts, buffalo currants, red huckleberries, eggplants, and brazil nuts. This could make CDP-ethanolamine a potential biomarker for the consumption of these foods.
