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 digestion of protein starts in the stomach, where HCl denatures the proteins and then pepsin begins to break them down into smaller polypeptides, which then travel to the small intestine (Figure 23.7.
