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.
Detailed explanation-2: -It is composed of water, mucus, proteins, mineral salts, and amylase. As saliva circulates in the mouth cavity it picks up food debris, bacterial cells, and white blood cells.
Detailed explanation-3: -Saliva contains the enzyme amylase, also called ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine.
Detailed explanation-4: -Saliva contains a digestive enzyme called Amylase, which begins to break down some carbohydrates present in the food before going down the mouth. Amylase is an enzyme that catalyzes starch hydrolysis into sugars. It is present in human saliva and in some other mammals, where the chemical process of digestion begins.
