Now, these enzymes play a role in digestion of carbohydrates into monosaccharides, in digestion of proteins into amino acids, dipeptides and tripptides, and fats into mostly fatty acids. Now, the small intestine doesn't only play a role in digestion, it also plays an important role in absorption. So all these individual constituent molecules are monosaccharides amino acids and fatty acids that are ultimately broken down from the carbohydrates. The proteins and fats are absorbed by the cells found in the small intestine, known as anterocytes. So interracytes absorb these nutrients and ultimately dump these nutrients into our blood system as well as into our lymph system. And these circulate through our body and eventually end up at the tissues and the cells that require those nutrients.
