Phosphatidylethanolamine

Phosphatidylethanolamine (PE) is a type of phospholipid, a molecule that forms a major part of cell membranes. It helps structure and maintain the integrity of cell membranes, allowing cells to function properly. PE is composed of a fatty acid tail, a glycerol backbone, and a phosphate group attached to an ethanolamine molecule. It is essential for various cellular processes such as membrane fusion, cell signaling, and the formation of certain organelles. Because of its critical roles, PE is vital for overall cell health and function.
