Enterokinase, also known as enteropeptidase, activates pancreatic enzymes in the small intestine. Its deficiency can cause digestive issues and failure to thrive, highlighting its critical role in nutrient absorption.

Area of Science:

  • Gastroenterology
  • Enzymology

Background:

  • Enterokinase (enteropeptidase) is a duodenal and jejunal glycoprotein crucial for activating pancreatic enzymes.
  • Pancreatic enzymes are secreted as inactive proenzymes, requiring activation in the duodenal lumen.

Purpose of the Study:

  • To review the role of enterokinase in digestive physiology.
  • To discuss the clinical implications of enterokinase deficiency and its association with gastrointestinal disorders.

Main Methods:

  • Literature review of enterokinase function and clinical significance.
  • Analysis of the pathogenesis of pancreatitis and malabsorption syndromes related to enterokinase.

Main Results:

  • Enterokinase converts trypsinogen to trypsin, initiating the pancreatic enzyme cascade.

  • Enterokinase deficiency, both congenital and acquired, leads to maldigestion, failure to thrive, hypoproteinemia, and edema.
  • Enterokinase's role in pancreatitis pathogenesis and its interaction with other digestive hormones are significant.

    • Conclusions:

    • Enterokinase is essential for normal protein digestion and overall gastrointestinal health.
    • Understanding enterokinase's function is vital for diagnosing and managing specific digestive diseases.
    • Further research is needed to elucidate the complex interplay between enterokinase, hormones, and bile salts.
