Q:

What is the optimum pH of salivary amylase?

A:

Quick Answer

The optimum pH of salivary amylase is approximately 6.7 to 7, according to Worthington Biochemical Corporation, meaning very slightly acidic. If the pH is significantly out of this range, the enzyme performs sub-optimally, and eventually becomes denatured, at which point it no longer functions, notes Encyclopaedia Britannica.
