title: Effect of ultrasound on activation of serine proteases precursors.
abstract: The effect of ultrasound (US) (26.4 kHz, 26 W/cm2) on the activation process of a mixture of chymotrypsinogen and trypsinogen was studied. US led to a significant decrease in proteolytic activity, as well as inhibition of the activation process in general. It was shown that inhibition of proteinase activity under US influence was a consequence of inhibition of chymotrypsinogen-chymotrypsin transformation and the complete proteolytic trypsin degradation in the proenzymes mixture.
