Document Summary

Best way to absorb protein is single amino acid, but we can also absorb as di or tripeptides. As babies> can absorb whole proteins> lose this ability. Majority of protein digestion within small intestine (even tho pepsin cuts in stomach) in duodenum. Enterokinase is a bb enzyme > form trypsin from trypsinogen > limitting step is enterokinase to produce trypsin > to make the other ximogens. 20 dif amino acids (neutral acidic, or basic amino acids)> so they have dif properties > need to have more enzymes to recognize them to cleave down into amino acids. Aminopeptidase cleaves last amino acid off, regardless of what the a acid is same for carboxypeptidase at c end. This is not efficient but we can liberate single amino acids. Enpeptidases are specific : target seq they recognize. Hopefully after will be recognized again and cut by endo and exopeptidaes. Not all amino transporters are cotransport with sodium.
