Another major theme is evolution, which explains the unity and diversity of life.

<span>Ptyalin hydrolysis does not continue in the stomach because it is destroyed by the stomach once it enter the stomach. </span>
Ptyalin is an amylase enzyme commonly found in the saliva of
humans and animals. This enzyme is secreted in the mouth ( buccal cavity) and catalyze
the hydrolysis of starch into maltose and dextrin. Immediately the starch
leaves the mouth and enter the stomach, stomach acids destroy the ptyalin.
