What is the optimum pH of pancreatic amylase?

Human pancreatic alpha-amylase. II. Effects of pH, substrate and ions on the activity of the enzyme. Purified human pancreatic alpha-amylase (alpha-1,4-glucan 4-glucano-hydrolase, EC was found to be stable over a wide range of pH values (5.0 to 10.5) with an optimal pH for the enzymatic activity of 7.0.

Also to know is, what is the optimum pH for amylase and why?

Effects of pH
EnzymepH Optimum
Maltase6.1 - 6.8
Amylase (pancreas)6.7 - 7.0
Amylase (malt)4.6 - 5.2

What is the optimum pH for amylase to work?

The pH is at alkaline levels in the mouth and small intestine, but the pH in the stomach is at acidic levels. The enzymes there work at different optimum pH levels. For example: salivary amylase works best just below pH 7.

What is the optimum pH level for salivary amylase?

The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denaturated. The enzyme salivary amylase is most active at pH 6.8.
