>>7611922Glycoproteins are integral membrane proteins covalently bonded to an oligosaccharide (short chain of carbohydrates) protruding from the membrane of the phospholipid bilayer and into the external environment surrounding the cell. The variety in bond type and structures in carbohydrates Allows glycoproteins to creat unique identification tags for cells (showing other cells especially the immune system what part of the body they belong). Glycoproteins are also useful in cell signaling/communication.
