Carbohydrates participate in cell recognition signals by being attached to what on the cell surface?

Carbohydrates act as recognition signals when they are covalently attached to proteins or lipids on the cell surface. These carbohydrate chains form glycoproteins and glycolipids, creating a sugary coat called the glycocalyx that sticks out from the membrane. The specific sugar patterns vary between cell types, so other cells and receptors can distinguish self from non-self and recognize signals for communication, adhesion, or immune responses. Nucleic acids, minerals, and water aren’t arranged on the cell surface in this recognition role, nor do they carry the distinctive sugar tags that cells use to identify one another.
