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: -Saliva is capable of chemically breaking down some large molecules, like carbohydrates, but it isn’t good at digesting proteins. The chemical digestion of proteins begins in your stomach.
