Chymotrypsinogen, III

Since the specific activities of pure porcine amylase (23), lipase (16), and trypsinogen (Section III, F) are known, approximate values for the percentage of the three enzymes in pig pancreatic juice can be estimated as stated above. These values are respectively 7.5, 2.5, and 24 % of the total proteins. By taking into account the specific activity of pure pig chymotrypsinogen A (Section III, D), a value of 14% is found for this class of precursors. However, the value is preliminary since the specific activity and the amount of the second chymotrypsinogen of pig are not yet known.
