We break down the protein into smaller peptides as a result of those proteolytic enzymes specifically the pepsin the enzyme that cleaves the peptide bonds in our proteins. Inside the stomach we have a very low PH and that denatures our proteins and allows Pepsin to actually cleave those bonds. And this hydrochloric acid also basically kills off bacterial cells that enter our stomach with our food. Now, although our stomach does actually absorb certain types of molecules such as, for example, caffeine as we mentioned earlier aspirin, as well as alcohol it acts mostly in digestion. It doesn't actually absorb the nutrients in the stomach. Where the nutrients are absorbed are in the small intestine as we'll see in the next lecture.
