Definition of Glycoprotein
Glycoprotein: A molecule that consists of a carbohydrate plus a protein.
Glycoproteins play essential roles in the body. For instance, in the immune system almost all of the key molecules involved in the immune response are glycoproteins.
A glycopeptide is similar in structure to a glycoprotein but has a shorter chain of amino acids.Source: MedTerms™ Medical Dictionary
