Structural characterization of a water-soluble beta-(1-->6)-linked D-glucan isolated from the hot water extract of an edible mushroom, Agaricus bitorquis.
A water-soluble polysaccharide, isolated from the hot aqueous extract of an edible mushroom, Agaricus bitorquis, was found to consist of d-glucose only. On the basis of total hydrolysis, methylation analysis, and NMR studies ((1)H, (13)C, TOCSY, DQF-COSY, NOESY, ROESY, HMQC, and HMBC), the structure of the repeating unit was established as -->6)-beta-D-Glcp-(1-->.
