The three different types (High Mannose, Complex and Hybrid) share a common core structure including the first two N-acetylglucosamine residues and the first three mannose residues. N-glycans have important structural functions. WebIgG antibodies contain N-linked glycans on the Fc portion of each heavy chain. The glycan on one heavy chain can either match the glycan on the other heavy chain (symmetrical pairing) or be different (asymmetrical pairing). These Fc glycans influence effector functions and can alter clearance rates.
