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: -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.

Detailed explanation-3: -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-4: -Four examples of chemical digestion are amylase in the saliva, hydrochloric acid in the stomach, pepsin in the stomach, and lipase in the small intestine. Amylase is an enzyme in the saliva that begins the process of digestion in the body. It breaks down carbohydrates into their monomers, monosaccharides.
