When the enzymes in the pancreatic juice pass through the intestinal tract, most of them are decomposed into amino acids which are reabsorbed by the small intestine, and only chymotrypsin is less damaged. Serum chymotrypsin assay can be used as an indicator of pancreatic exocrine function to a certain extent.
