What is the structure of glycoprotien?

Glycoproteins are proteins that have carbohydrate chains (glycans) covalently attached to their polypeptide backbone. The structure typically consists of a core protein, which can be either a single polypeptide or a complex of multiple subunits, with one or more oligosaccharide chains attached. These carbohydrate components can vary in length and complexity, influencing the protein's stability, localization, and function. Glycoproteins play crucial roles in cellular recognition, signaling, and immune responses.
