Why can't insulin be given orally to diabetic patients?
Insulin is a polypeptide hormone that gets proteolytically degraded by gastrointestinal enzymes if ingested orally.
Insulin is a 51-amino-acid peptide hormone. When administered orally, gastric pepsin and pancreatic endopeptidases (trypsin, chymotrypsin) digest it into inactive amino acids before systemic absorption.
