Studies on the Carbohydrates extracted from Human Placenta. III

Configuration of the Hexasaccharide Composed of Glucoses

Abstract

α-Glucosidase was applied to the hexasaccharide, composed of glucose, extracted from human placenta, but no change in the reducive action was observed. On the other hand, application of β-glucosidase resulted in the increase of reducive action and glucose alone was detected as the reaction product. From these and previously reported results, it may be concluded that this hexasaccharide is composed of 6 molecules of glucose bonded in β-type, C₁ to C₄, in a chain.
