mucoprotein

General term for a protein-polysaccharide complex, usually implying that the protein component is the major part of the complex, in contradistinction to mucopolysaccharide; mucoproteins include the α₁- and α₂-globulins of serum (and others). Sometimes called glycoproteins, although this term usually refers to those mucoproteins containing less than 4% carbohydrate.

n.

one of a group of proteins found in the globulin fraction of blood plasma. Mucoproteins are globulins combined with a carbohydrate group (an amino sugar). They are similar to glycoprotein but contain a greater proportion of carbohydrate.

mu·co·pro·tein (mu″ko-proґtēn) a covalently linked conjugate of protein and polysaccharide, the latter containing many hexosamine residues and constituting approximately 4 to 30 per cent of the weight of the compound; mucoproteins occur mainly in mucous secretions. Cf. glycoprotein.
