what do the carbohydrate chains do for the plasma membrane
Glycoproteins. Glycoproteins are integral membrane proteins. Like glycolipids, they have short carbohydrate chains covalently attached which are exposed on the outer surface of the cell. Integral proteins are those which penetrate the hydrophobic region of the plasma membrane.lycoproteins. Glycoproteins are integral membrane proteins.
