Detailed explanation-1: -The chemical reaction that’s central to chemical digestion is called hydrolysis. It’s the process of incorporating water molecules into larger molecular structures. This breaks them down into smaller parts and makes it much easier for your cells to absorb the nutrients in your food.

Detailed explanation-2: -Digestion of food involves both mechanical and chemical processes. Through digestion, large food particles are converted into smaller components that can be readily absorbed into the bloodstream.

Detailed explanation-3: -Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.

Detailed explanation-4: -Chemical digestion begins in your mouth. As you chew, your salivary glands release saliva into your mouth. The saliva contains digestive enzymes that start off the process of chemical digestion.
