digested by proteases.
- some protein digestion begins in stomach → where stomach protease digests proteins into polypeptides.
- undigested proteins that enter small intestine → are digested by intestinal proteases into polypeptides
- Polypeptides produced → further digested to amino acids by intestinal proteases. (**Could be Pancreatic Proteases as well I suppose)
end product of protein digestion - amino acids - which can be absorbed; small, soluble, simple diffusible
