Study Notes
Carbohydrate Absorption in the Gastrointestinal Tract (GIT)
- The main form of carbohydrates that is absorbed in the GIT is monosaccharides.
Enzyme Activation and Function
- Salivary amylase is activated in a pH range of 6.7-7.7.
- Salivary amylase converts polysaccharides to disaccharides in the mouth.
- Another enzyme, pancreatic amylase, continues to break down polysaccharides to disaccharides in the small intestine.
- Sucrase, an enzyme in the small intestine, is responsible for the hydrolysis of sucrose to fructose and glucose.
- Gastric acid, which has a low pH, stops the enzyme action of salivary amylase in the stomach.
