GIP (6-30), human, 1mg

GIP (Glucose-dependent Insulinotropic Polypeptide or also known as Gastric Inhibitory Polypeptide) is a 42-amino acid peptide released by the K cells of the duodenum and jejunum in response to food intake. GIP (6-30) is a short active version of the 42-amino acid long peptide. Together with GLP (Gastric-like Peptide) these peptides are members of the hormone peptide family of incretins which stimulate insulin secretion from pancreatic islet β-cells, and also appears to promote beta cell proliferation and beta cell survival. Recent studies suggest that GIP plays a role in lipid homeostasis and possibly in the pathogenesis of obesity.
