What is the major function of the glycocalyx?

The glycocalyx is a gel-like layer on the outside of the plasma membrane composed of glycoproteins and glycolipids. Its major function is to facilitate cell-cell interactions and attachment. This structure plays a crucial role in cellular communication and adhesion, allowing cells to recognize and interact with each other. This is essential for various physiological processes, including tissue formation, immune responses, and maintaining the integrity of cellular structures.

In addition, the glycocalyx can contribute to the creation of a protective barrier that helps maintain a suitable environment around the cell. However, its primary role revolves around enabling cells to attach to one another, which is vital for the organization of tissues and the overall functionality of multicellular organisms.
