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.
Four of the enzymes have special importance in digestion of food by humans. 1  Amylase from our salivary glands and pancreas digests starch to maltose in our mouth and small intestine. 2  Lipase from the pancreas digests lipids to fatty acids and glycerol in our small intestine. Pepsin is a protease that begins digestion of proteins, breaking them into peptides and amino acids. Pepsinogen, is secreted by gastric glands of the stomach into the stomach.
