What is "phosphatidylethanolamine"

n. (context organic chemistry English) Any of a class of phospholipid containing ethanolamine

Phosphatidylethanolamines (sometimes abbreviated PE) are a class of phospholipids found in biological membranes. They are synthesized by the addition of CDP- ethanolamine to diglycerides, releasing CMP. S-Adenosyl methionine can subsequently methylate the amine of phosphatidylethanolamines to yield phosphatidylcholines. It can mainly be found in the inner ( cytoplasmic) leaflet of the lipid bilayer.
