| phospholipid |
Main lipid component of cell membranes. Phospholipids are a heterogeneous type of molecule composed of glycerol, phosphate, two fatty acid residues, and 'headgroups' with different chemical properties. The organization of phospholipids in cell membranes is known as phospholipid bilayer where the fatty acid residues face the center of the membrane (hydrophobic or water insoluble) and the headgroups forming the surface of the membrane. ...

| phospholipid |
These molecules make up an important part of cell membranes. They are made up of a phosphate component and a lipid component. The lipid is water-hating, while the phosphate is water-loving. These properties help determine the structure of a membrane and facilitate the movement of material in and out of the cell.
