Structural Characterization of a Neutral Β-D-Glucan-Containing Fraction Isolated from the Basidiomycete Fungus Fomes fomentarius By NMR Spectroscopy

Background

Fungal β-glucans are structurally diverse polysaccharides whose linkage patterns and branching characteristics influence their physicochemical properties. Fomes fomentarius contains chemically heterogeneous polysaccharide fractions; however, fraction-specific structural information on neutral polysaccharides isolated from naturally occurring fruiting bodies remains limited. Detailed NMR-based characterisation is therefore important for clarifying the glycosidic linkage and substitution patterns of purified β-glucan-containing fractions.
