The structure and conformation of a water-insoluble (1→3)-,(1→6)-β-d-glucan from the fruiting bodies of Pleurotus florida

A water-insoluble glucan, PFPSIN, has been isolated from the aqueous extract of an edible mushroom Pleurotus florida. On the basis of total acid hydrolysis, methylation analysis, periodate oxidation, Smith degradation, and 13C NMR experiments, the repeating unit of the polysaccharide was established as Figure optionsDownload full-size imageDownload as PowerPoint slide Conformational analysis revealed the triple helical conformation of this glucan.
