FIGURE 8.1. Types of N-glycans.



The original drawing depicted a hybrid chain containing two outer α2-linked mannose residues, which is not known to occur in nature. The correct structure contains only five mannose residues.

Types of N-glycans. N-glycans added to protein at Asn-X-Ser/Thr sequons are of three general types in a mature glycoprotein: oligomannose, complex, and hybrid. Each N-glycan contains the common core Man3GlcNAc2Asn.
