INHIBITORY EFFECT AND ENZYMOLYSIS KINETICS OF LENTINAN ON Α-GLUCOSIDASE
Objective: To study the inhibitory activity and enzymolysis kinetics of lentinan on α-glucosidase.Methods: The enzyme-agent screening model was used to investigate the optimal conditions of α-glucosidase action.In vitro enzyme kinetics was studied by changing the substrate concentration,reaction time,pH conditions and temperature.Results: The optimal reaction conditions of α-glucosidase were reaction time 120min,reaction temperature 50℃,buffer pH 6.0,concentration of substrate PNPG 0.1089 mol/L.Conclusion: 1g/L concentration of lentinan has good inhibitory activity against α-glucosidase,and the inhibitory effect of lentinan is competitive inhibition.
