DescriptionCDP-Ethanolamine, also known as CDP ethanolamine, 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). CDP-Ethanolamine exists in all living species, ranging from bacteria to humans.

Enzymes

General function:
Involved in phosphotransferase activity, for other substituted phosphate groups
Specific function:
Involved in protein-dependent process of phospholipid transport to distribute phosphatidyl ethanolamine to the lumenal surface. The multiple transmembrane domains and lumenal hydrophilic domains of the ethanolaminephosphotransferase might participate in the transport process. EPT1 catalyzes both choline- and ethanolamine-phosphotransferase reactions
