Best Answer: Probably the same as any other major... probably even shorter than some (such as pre-med), so 4 years. For my school, you need Intro, Research Methods ...
Digestion of foods in the small intestine. The small intestine continues the process of digestion and various enzymes are present there to break starches down further. These enzymes are called disaccharidases. The best known is lactase, which is the enzyme necessary to digest milk sugar. This enzyme is normally present in all young mammals who need this to digest mother's breast milk. With age and as breast feeding finishes, production of this enzyme ceases for life.
Digestive enzymes are small proteins that act on specific molecules within foods to break them down. Most people are familiar with the enzyme lactase, which is responsible for breaking down the milk sugar called lactose. People who are missing this enzyme are not able to digest milk (known as âlactose-intoleranceâ).
