Answer
Oligosaccharide chains of glycoproteins are chemical markers used to tag proteins by attaching to it at either of N- or O-glycosidic bonds. O-linked oligosaccharides are short as they have only one to four sugar residues while on the other hand N-linked oligosaccharides exist in wide varieties. N-linked oligosaccharides consists of a pentasaccharide core that has three mannose and two N-acetylglucosamine residues. Along with additional sugars can be attached to the core to form large variety of oligosaccharide.
