Abstract

Glycogen extracted from liver of type II glycogenosis was studied pbysicochemically. Its infra-red absorption spectrum wave showed a typical α-polysaccharide. Electron micrographs of the extracted glycogen with negative staining procedure revealed a large branching structure very similar to the normal control liver glycogen. The Cotton effect was not observed in the ORD and CD absorption spectra wave. Tbe degree of β-amylolysis and the average chain length were slightly greater than that of the normal control glycogen. The sedimentation coefficient had a larger s value than normal glycogen.
