Structure Diversity of Oligosaccharide Chains

1 N-linked oligosaccharide chain. An N-glycosidic bond to the side-chain 

N-linked glycose chains contain an GlcNAc residue at their reducing termini and are linked 

N-linked Man-rich oligosaccharides are synthesized on a specific lipid (dolicholphosphate) then added to protein molecules prior to their translocation. The 

Six amino acids, namely Cys, Asp, Asn, Gly, Ala and Ser (CDNGAS), serve as a GPI attachment site. This attachment is common for the surface coat-protein of certain parasites and manbrane enzymes.
