Detailed explanation-1: -This indicates that saliva has a major physiologic role in food digestion [7]. The most abundant protein in human saliva is the digestive enzyme -amylase [8].

Detailed explanation-2: -Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.

Detailed explanation-3: -Amylase is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates into easier to absorb simple sugars. Salivary amylase is the first step in the chemical digestion of food.

Detailed explanation-4: -Salivary amylase or ptyalin has one major role to keep bacteria in the mouth in control. They are being activated by chloride ions. Chloride ions are present in the enzymes and act as activators to activate the enzyme so that they can be put into action.

Detailed explanation-5: -Ptyalin is the starch hydrolyzing enzyme secreted by salivary glands in human beings. It is also called as salivary amylase.
