why intestinal proteases secreted in an inactive form?
Enzymes acting on proteins are called proteases. Stomach proteases and pancreatic proteases are secreted in inactive form so that they could not damage the organ in absence of the food by digesting the wall proteins. These enzymes are activated only in presence of food. Intestinal proteases are secreted in active form (dipeptidases) and enterokinase of intestinal juice activates the pancreatic proteases.
