Welcome to Annieâs Chamorro Kitchen! My name is Annie ~ food and I get along so well! Cooking and baking is more than a hobby for me ~ it's a passion. I come from the beautiful island of Guam, U.S.A., which is located in the beautiful southwest Pacific.
The digestion of different types of foods occurs in different areas of the digestive tract. Digestion of starch begins in the mouth with the chewing of food (mastication) and the production of amylases immediately breaking down certain starches.
Summarize chemical digestion. 1  Protein digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.  During carbohydrate digestion, bonds between glucose molecules are broken by salivary and pancreatic amylase.
