A water-insoluble (1-->3)-beta-D-glucan from the alkaline extract of an edible mushroom Termitomyces eurhizus.
A water-insoluble glucan, TEINS has been isolated from the hot alkaline extract of an edible mushroom Termitomyces eurhizus. The total carbohydrate content of the polysaccharide fraction was found to be 98.4%, and it was found to contain only glucose as the monosaccharide constituent. On the basis of total acid hydrolysis, a methylation experiment, periodate oxidation and (13)C NMR experiment, the repeating unit of the polysaccharide was established as: -->3)-beta-D-Glcp-(1-->.
