What are the enzymes in the pancreatic juice?
Pancreatic juice is composed of Bicarbonate, Trypsinogen, Chymotripsinogen, Proelastase, Procarboxypeptidase A, and Procarboxypeptidase B. All of these proenzymes (except Bicarbonate, which isn’t a proenzyme) are inactive in the pancreas. They must travel to the lumen of the Small Intestine before they are activated by enteropeptidase, which converts Trypsinogen to Trypsin, cascading to convert the other proenzymes to their active forms and working to break peptide bonds to that enterocytes can absorb the broken down peptides.
