              Activity:
              Activity is measured by inhibition of pepsin. 1 U corresponds to the amount of inhibitor that reduces the activity of pepsin by 1 U (1 U of enzyme corresponds to the amount of enzyme that results in the increases the absorbance at 280 nm by 0.001 per min at pH 2.0, 37°C.)
