Glycoproteins are membrane carbohydrates covalently bonded to which molecule?

Explanation:
Glycoproteins are proteins with carbohydrate groups covalently attached. This means the sugar chains are linked to amino acid residues on the protein backbone (commonly N-linked to asparagine or O-linked to serine/threonine), producing a protein that carries extracellular carbohydrate branches. If the carbohydrate were bound to a lipid, you’d have a glycolipid, not a glycoprotein. Nucleic acids aren’t the typical covalent partner in this context, and while carbohydrates can attach to other carbohydrates in other molecules, the defining feature of a glycoprotein is its covalent bond to a protein.
