Cell surface carbohydrates are essential components of the plasma membrane and are primarily present as glycoproteins and glycolipids. These carbohydrate chains extend outward from the cell surface, forming a carbohydrate-rich layer known as the glycocalyx. Their structural diversity and specific spatial arrangement enable cells to recognize and interact with one another in a highly selective manner. In cell–cell recognition, surface carbohydrates act as molecular identity markers. Differences in carbohydrate composition help cells distinguish self from non-self and identify cell types, developmental stages, and physiological states. For example, specific
