Formaecin 1

Gastric Inhibitory Peptide (GIP), human

Metabolic

Gastric Inhibitory Peptide (GIP), also known as glucose-dependent insulinotropic polypeptide, is a 42-amino acid incretin hormone naturally produced by K-cells in the duodenum and jejunum of the small intestine. GIP plays a crucial role in glucose homeostasis and metabolic regulation by stimulating insulin secretion in a glucose-dependent manner, meaning it only promotes insulin release when blood glucose levels are elevated. This peptide also inhibits gastric acid secretion and gastric motility, hence its original name. GIP functions through binding to GIP receptors (GIPR), which are G-protein coupled receptors found primarily in pancreatic beta cells, but also in adipose tissue, bone, and brain. The hormone is released postprandially in response to nutrient intake, particularly glucose and fatty acids. In addition to its insulinotropic effects, GIP influences lipid metabolism, bone formation, and may have neuroprotective properties. Research has shown that GIP's actions are impaired in type 2 diabetes, leading to interest in GIP receptor agonists as potential therapeutic agents. The peptide's dual role in glucose regulation and metabolic control makes it an important target for understanding and treating metabolic disorders, obesity, and diabetes.
