Document Summary
How to bring substances into our body in the form of aa, breaking fat into triglycerides, proteins into smaller peptides and aa that we can then more readily utilize. Recall: gi secretion and absorption several ways that the body facilitates movement of water fromgi tract to the rest of the body. Types of transport several different mechanisms by which material crosses epithelial cells (barrier between you and ext environment) transcellular: movement from apical surface to basolateral surface (on various transporters, such as nag) Ultimate role of gi tract is absorption of nutrients. Usually carbs in western diet is from sucrose. Must be broken down into monosaccharides befrore they may be transporterd into the body. Amylase breaks up those starches into smaller chains into disaccharides, and then enzymes called disaccharidases break up disaccharides further into monosaccharides, which may then be digested. Absorb them as aa, but may also absorb them as a small molecules.
