Abstract:
The effect of various cationic surfactants on the initial rate of the 5-aminosalicylic acid peroxidation with horseradish peroxidase was studied. With increasing concentration of the surfactant, the rate first increased and then decreased. We attributed these changes to a primary activation of the enzyme and/or an increase in the concentration of the substrate in the region of the active site and to the subsequent inactivation of the protein with surfactant followed by its denaturing, respectively.

Factors Affecting Activity Coefficient
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a decrease in the...
