Simplified Representation of Oligosaccharide and Polysaccharide Structures

6-glucopyranosyl 6-nigerosyl maltose alteman pentasaccharide 2,6 -di-O-D-gluco 

When carbohydrate residues are combined together, only the glycosidic bond need be shown. This is illustrated for the eight a- and P-glucodisaccharides that have the 1 — 2,1 3,1 4, and 1 6 glycosidic hnkages (see Fig. 6.23B and C). 

More complex tri, tetra-, and pentasaccharides, each with more than one type of glycosidic linkage, can also be represented, as shown in Fig. 6.23D. When
