Explanation:
Detailed explanation-1: -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-2: -The chemical digestion of carbohydrates and lipids begins in the mouth through the actions of salivary amylase and lingual lipase respectively. Unlike carbohydrates and lipids, the enzymatic digestion of proteins starts in the stomach and is carried out by the enzyme pepsin.
