a lipid containing a phosphate group as part of the molecule. Phospholipids are constituents of all tissues and organs, especially the brain. They are synthesized in the liver and small intestine and are involved in many of the body's metabolic processes. Examples of phospholipids are cephalin, lecithin, plasmalogens, and phosphatidylserine.
