Detailed explanation-1: -Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands. It comprises a small portion of the total amylase excreted, which is mostly made by the pancreas.

Detailed explanation-2: -Ptyalin is the starch hydrolyzing enzyme secreted by salivary glands in human beings. It is also called as salivary amylase. Ptyalin secreted in the mouth brings about digestion of starch in the mouth itself. They break down carbohydrates into smaller molecules like sugars.

Detailed explanation-3: -For example, there are enzymes in our saliva, pancreas, intestines and stomach. They break down fats, proteins and carbohydrates. Enzymes use these nutrients for growth and cell repair.

Detailed explanation-4: -[13] The greatest S-type amylase activity is in salivary glands, where it initiates the hydrolysis of starches while food is in the mouth and esophagus.
