Objective #18 (con’t: protein digestion)
- proteins
- proteases digest proteins into amino acids
- secreted by pancrease and intestine
- pancreatic proteases include trypsin, chymotrypsin and carboxypolypeptidase
- secreted as inactive precoursers to protect intestinal mucosa from being digested
- trypsinogen, chymotrypsinogen, and procarboxypolypeptidase, respectively
- cleave large proteins into small peptides
- intestinal proteases
- include aminopeptidase, carboxypeptidase, dipeptidase
- cleave small peptides into amino acids
