The complex of sugar polymers and proteins which are patchily distributed on the plasma membranes of animal cells is called
Proteins that are sent to the cell surface are often glycoproteins (have sugars attached to them). Glycolipids (lipids with sugar attached) are also found on the outer surface of the plasma membrane. All these sugars on the cell surface form a dense carbohydrate coat called the glycocalyx on the outside of the cell.
