Detailed explanation-1: -There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

Detailed explanation-2: -The major types of enzymes involved in the chemical digestion of food are protease, amylase, and lipase. Protease digests proteins into amino acids while amylase digests carbohydrates into simple sugars and lipase breaks down lipids into fatty acids.

Detailed explanation-3: -This allows the nutrients from these foods to be easily absorbed into your blood and carried through your body. There are several digestive enzymes, including amylase, maltase, lactase, lipase, sucrase, and proteases.

Detailed explanation-4: -Chemical digestion, through a process called hydrolysis, uses water and digestive enzymes to break down the complex molecules. Digestive enzymes speed up the hydrolysis process, which is otherwise very slow.
