Unformatted text preview: Ryan Sanders 1/31/06 p. 1 Digestive Enzyme Supplement Lab Introduction A digestive enzyme is a protein that breaks down specific substances into chemicals that can be used in the body. Some examples are Amylase, Pepsin, and Lactase. Salivary Amylase is found in the salivary gland, its substrate is carbohydrates, and it turns starch into glucose. Lactase is found in the small intestine, its substrate is Lactose, and it turns lactose into glucose. Pepsin is found in the stomach, its substrate is protein, and it turns proteins into dipeptides. Pancreatic Amylase is found in the pancreas, its substrate is Carbohydrates, and it turns starch into glucose. Pancreatic Lipase is found in the pancreas, its substrate is lipids, and it turns fats into fatty acids and glycerol. Pancreatic Trypsin is found in the pancreas, its substrate is protein, and it turns proteins into dipeptides. In our experiment, we have 3 enzyme supplements: Lactase, Pepsin, and Pancreatin. Lactase mimics milk, pepsin mimics protein, and pancreatin mimics proteins, carbohydrates and lipids. These enzymes are taken from animal or plant sources or they are grown from bacteria using recombinant DNA technology. Question Do digestive enzyme supplements sold at health food stores really mimic natural enzymes found in our bodys alimentary canal?...
