Figure 8.

Structure and composition of N-linked glycans. (A) The Asn-linked core oligosaccharide is composed of two N-acetylglucosamines (squares), nine mannoses (circles; the cleavable α1,2-bonded mannoses are shown in dark green), and three glucoses (triangles). The linkages are indicated, and letters a–n are assigned. a–c define the three oligosaccharide branches. (B) Aberrant oligosaccharide transferred to nascent polypeptide chains in B3F7 cells (Moremen and Molinari, 2006).
