摘要：

The distribution of the acetamide group in partially deacetylated chitins (DAC) was investigated by nitrous acid deamination. Deamination products of various DAC (DAC-66, DAC-77, DAC-84 and DAC-91) were mainly trisaccharide, disaccharide, and monosaccharide. These results would suggest random distribution of the acetamide group in the DAC molecule prepared by heterogeneous deacetylation.
