The plasma membrane is mostly made of phospholipid molecules that have a hydrophilic head and a hydrophobic tail. These phospholipids form a bilayer structure that gives the membrane its selective permeability. Proteoglycans, glycolipids, and glycoproteins are also found in the membrane, but they are not the primary molecules that make up the structure of the membrane. Lipoproteins are not part of the membrane structure at all, but rather a type of molecule involved in lipid transport.
