Figure 1.6 Complex Saccharide Structures of Glycoproteins. A large number of complex-type structures are possible and those shown in this figure illustrate some typical features. Fucose is commonly, but not always, found linked to C-6 of the first residue of A/-acetyl-glucosamine. Rarely short hetero-saccharide sequences occur linked to C-3 of either or both of the A-acetylglucosaminyl residues of the di-A-acetylchitobiosyl sequence. The attachment of A-acetylglucosamine to C-4 of the P-mannosyl residue is another variable feature. The outer chains vary in number and may be linear or branched, complete or incomplete and of various lengths. Sequences with two linear outer chains are termed biantennate , those with three are triantennate etc. (Yoshima, Furthmayr and Kobata, 1980 Yoshima, Takasaki and Kobata, 1980 Kornfeld, 1978.)...
