Glycerophospholipids phosphoglycerides

The structure of glycerophospholipids is characterized by a l,2-diacyl-3-phospho-5n-glycerol, or phosphatidyl moiety, and a variable headgroup linked to the phosphate. Major phosphoglycerides found in nature are phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylserine, phosphatidylinositol (PI), and diphospha-... 

Glycerophospholipids Glycerophospholipids or phosphoglycerides are glycerol-based phospholipids. They are the main component of biological membranes. 

The most abundant phospholipids are those with the general formula (46a) where R is a long-chain fatty-acid residue as above, and X can be various groups. They are derivatives of glycerophosphoric acid (5.346) and are sometimes called glycerophospholipids or phosphoglycerides.
