Glycoproteins

Glycoproteins are proteins attached covalently to carbohydrate chains.The proteins are embedded in the membrane so the carbohydrate chains are on the cell surface.These act as recognition sites and antigens.The immune system is able to distinguish between the body's own cells and foreign cells through cell surface antigens.The carbohydrate chains also act as cell adhesion molecules.
