A gel-forming (1→3)-β-D-glucan isolated from cyttaria harioti fischer
An alkali-soluble glucan, [α]D + 11° (M potassium hydroxide) having a degree of polymerization of 220, has been isolated from the fruit bodies of the tree fungus Cyttaria harioti Fischer. Periodate oxidation and methylation analysis show that it consists of a highly branched β-D-(1→3)-linked backbon...
