FAQ
Frequently Asked Questions
No. Enterokinase is the enzyme that activates trypsinogen, converting it into the active digestive enzyme trypsin.
Enterokinase is produced and secreted by the mucosa (lining) of the duodenum, which is the first part of the small intestine.
Enterokinase deficiency impairs protein digestion because trypsinogen cannot be activated. This leads to malabsorption, diarrhoea, and poor growth, particularly in infants.
While pancreatic enzyme supplements are common for conditions like pancreatitis, enterokinase itself is not a standard supplement. Treatment for its deficiency typically involves providing already-activated pancreatic enzymes.
