Comparative Stability of Trypsin and Chymotrypsin in Human Intestinal Juice

Abstract

The stability of trypsin and chymotrypsin was determined in human intestinal juice. On a weight per weight basis at the end of one-half hour as much as 63% of chymotrypsin was still enzymatically active while only 8% of the trypsin activity could be detected. In fact, 30% of the chymotrypsin still remained at the end of 2 hours.
