Examples of structures of some polysaccharides. A. Curdlan; B. Schizophyllan; C. Lentinan; D. Pestolotan; E. Epiglucan. A-E: β-(1 3)(1 6) glucans [2]. F. a β-(1 4)-galactomannan with a branched chain of α-(1 6)-galactose [3]. G. a α-(1 4)-glucan with a side chain consisting of terminal and α-(1 4)-glucopyranosyl residues is attached at position O-6 of the branching residues [4]. H. a xylan with the 4-O-methyl-d-glucopyranosyluronic acid group linked to O-2 of a β-(1 4)-xylan [5]. I. an inulin-type fructan [6].
