The structure of an α-D-glucan from Cyttaria harioti Fischer
A homogeneous glucan has been isolated from the fruiting bodies of Cyttaria harioti Fischer. Partial acid hydrolysis produced major amounts of isomaltose, whereas acetolysis gave maltose and maltotriose. Enzymic hydrolysis with amylo-glucosidase and pullulanase indicated a structure based on maltotr...
