Gastric inhibitory peptide (GIP) a digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine.
- A member of the secretin family of hormones, glucose-dependent insulinotropic polypeptide is an inhibitory hormone.
- It is sometimes referred to as gastric inhibitory polypeptide or stomach inhibitory peptide.
- The enteroendocrine K-cells, which are widespread in the small intestine secrete GIP.
- The hormone gastric inhibitory polypeptide, which is released by intestinal mucosal cells, prevents the stomach from producing hydrochloric acid.
- Additionally, it improves the islets of Langerhans' beta cells' ability to secrete insulin, which results in a considerable increase in blood insulin concentrations following oral glucose delivery.
