If we isolated a cell from our body, we would notice that it is surrounded by a kind of mesh made of loosely interwoven carbohydrate (carbohydrate) molecules.

This mesh protects the cell like a garment: it is the glycocalyx (from Greek glykys, sweet, sugar, and latin calyx, shell wrap).

Several functions have been suggested for glycocalyx. It is believed that, besides being a protection against physical and chemical aggression from the external environment, it acts as a nutrient and enzyme retentionby maintaining a suitable microenvironment around each cell. Gives cells the ability to recognize each other, since different cells have glycocalyx formed by different glycids and equal cells have glycocalyx formed by equal glycids.
