Saccharogenic method principle

WebSaccharogenic methods, on the other hand, monitor the generation of reducing groups. Inasmuch as each hydrolytic cleavage induced by α-amylase creates a new reducing group, this increase is directly proportional to the enzymatic activity. References (57) A.C. Kibrick et al. J. Biol. Chem. (1951) V.C. Myers et al. J. Biol. Chem. (1944) WebThe major principles of assay on which the various methods of determining amylase activity are based are as follows: 1. Decrease in viscosity of a starch solution. 2. Decrease in turbidity of a starch suspension. 3. Diminution in the .starch-iodine color. 4. Increase in the reducing power of starch solution.
