Detailed explanation-1: -Chemical digestion in the mouth is minor but consists of salivary amylase (ptyalin, or alpha-amylase) and lingual lipase, both contained in the saliva. Salivary amylase is chemically identical to pancreatic amylase and digests starch into maltose and maltotriose, working at a pH optimum of 6.7 to 7.0.
Detailed explanation-2: -Saliva plays an important role in chemical digestion. As the teeth break food into smaller pieces, saliva mixes with the food. Chemicals called enzymes, found in saliva, break down food into smaller pieces.
Detailed explanation-3: -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.
