Plasma membrane

The plasma membrane is the external cell membrane It is composed of a double lipid layer (mostly phospholipids but also cholesterol and glycolipids) into which various proteins are inserted (such as receptors, transporters and enzymes). The plasma membrane has selective permeability: fat soluble molecules and gases cross it easily, whereas only some water-soluble molecules cross it through specific transporters for each molecule.
