Detailed explanation-1: -Chemical digestion in the mouth is minor but consists of salivary amylase (ptyalin, or alpha-amylase) and lingual lipase, both contained in the saliva. Salivary amylase is chemically identical to pancreatic amylase and digests starch into maltose and maltotriose, working at a pH optimum of 6.7 to 7.0.
Detailed explanation-2: -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-3: -In chemical digestion, food is broken down by the action of chemical agents (such as enzymes, acids and bile)
