Phosphatidylethanolamine
Phosphatidylethanolamine
Phosphatidylethanolamine (pronunciation: fos-fa-tid-yl-eth-anol-amine) is a class of phospholipids found in biological membranes. It is synthesized in the cell from ethanolamine and phosphatidic acid.
Etymology
The term "Phosphatidylethanolamine" is derived from the combination of the words "phosphatidyl", referring to the presence of a phosphate group, and "ethanolamine", indicating the presence of an ethanolamine group.
Function
Phosphatidylethanolamine plays a crucial role in cell membrane structure and function. It is involved in the fusion of membrane vesicles and in apoptosis, a process of programmed cell death. It also acts as a precursor for the synthesis of other important phospholipids, such as phosphatidylserine.
