Question

starch is digested by amylase in mouth, but it is not digested in the stomach. what is the reason for this?

Answer 1

Step-by-step explanation:

Only about five percent of starches are broken down in the mouth. (This is a good thing as more glucose in the mouth would lead to more tooth decay.) When carbohydrates reach the stomach no further chemical breakdown occurs because the amylase enzyme does not function in the acidic conditions of the stomach.
