The action of potato inhibitors on activation of zymogen forms of digestive system proteases.

The potato inhibitors of proteases inhibit the activation of trypsinogen, chymotrypsinogen, proelastase, procarboxypeptidase A and B induced by trypsin. These inhibitors do not inhibit the activation of trypsinogen induced by enterokinase. Potato inhibitors have no influence on pepsinogen autoactivation and on pepsin activity.
