pH is normally used to find whether the compound is acidic or basic. The optimum pH value means the point in which the enzyme activity is more. All the enzymes are made up of proteins which are specifically reactive at a particular pH.
The enzymes need that exact physical and chemical parameter to continue with their enzymatic reactions.
The optimum pH of intestinal protease is generally around 8.0. Protease intestinal activity was found to be lower at 6.0 and was found to be maximum at 8.0
