A third method of detecting inhibitors, of rather limited utility, is the observation of multiple pH-activity optima for what is otherwise a pure enzyme. For example, Schwlmmer ( 6) observed that potato invertase showed a double pH optima. It was discovered that the explanation of the double pH optima was due to an invertase inhibitor in the potato (, ) This observation is shown schematically in Figure 1. 

Many cereals and cereal products (such as wheat, rye, breakfast cereals and bread) contain proteins inhibiting animal, but not plant amylases. Invertase inhibitors are found in potato tubers, for example. The significance of these enzyme inhibitors is neghgible and the consequences of their presence in food are not yet known. It is beheved that amylase inhibitors could potentially be used in preparations for diets to promote weight loss.
