Summary
1. For glucobioses with a β-glycosidic linkage the following sequence of rates of acetolysis according to the type of bond has been found: 1,1>1,6>1,3>1,4>1,2.
2. It has been established that when a glucose residue in a disaccharide is replaced by a galactose residue, the resistance of the glycosidic linkage to acetolysis decreases.
3. The high reactivity of disaccharides having 1,6-glycosidic linkages has been explained.
4. The ratios of penta- and heptaacetates from some glucobioses have been determined by the GLC method.
