Glycopeptides are peptides that contain carbohydrate moieties (glycans) covalently attached to the side chains of the amino acid residues that constitute the peptide.

They may bind to a soluble carbohydrate or to a carbohydrate moiety that is a part of a glycoprotein or glycolipid.

As such xylose constitutes the second most abundant carbohydrate moiety in nature.

Studies of the 200 kDa glycoprotein antibodies found them commonly in healthy people, suggesting that the disease associated antibodies are to their carbohydrate moieties.

In addition, purified native draculin, obtained from high- and low-activity saliva, shows significant differences in composition of the carbohydrate moiety, and glycosylation pattern.

The carbohydrate moieties of avidin contain at least three unique oligosaccharide structural types that are similar in structure and composition.

The structures of the polypeptide chain and carbohydrate moieties of bovine lactoferrin (bLF) are well established.

This coating consists of several carbohydrate moieties of membrane glycolipids and glycoproteins, which serve as backbone molecules for support.

Glycosylation also plays a role in cell-cell adhesion (a mechanism employed by cells of the immune system) via sugar-binding proteins called lectins, which recognize specific carbohydrate moieties.

AFP is a glycoprotein of 591 amino acids and a carbohydrate moiety.
