Definition

A cell‑associated layer of carbohydrates and carbohydrate‑modified molecules on the plasma membrane composed primarily of glycoproteins, glycolipids and proteoglycans; it forms a nanoscale interface that mediates cell–cell and cell–molecule interactions, modulates receptor accessibility and shear sensing, and contributes to mechanical and chemical protection of the cell surface.
