Metabolite Identification
Common NamePhosphatidylethanolamine
DescriptionPhosphatidylethanolamine (cephalin, sometimes abbreviated PE) is a lipid found in biological membranes. It is synthesized by the addition of CDP-ethanolamine to diglyceride, releasing CMP. S-adenosyl methionine can subsequently methylate the amine of phosphatidyl ethanolamine to yield phosphatidyl choline. Cephalin is a phospholipid, which is a lipid derivative. It is not to be confused with the molecule of the same name that is an alkaloid constituent of Ipecac. (Wikipedia)
