Studies on peptides. 63. Synthesis of the octacosapeptide corresponding to positions 1 through 28 of porcine gastric inhibitory polypeptide (GIP).

Abstract
The octacosapeptide amide corresponding to positions 1 through 28 of porcine gastric inhibitory polypeptide (GIP) was synthesized in a conventional manner. This peptide fragment of GIP exhibited no suppression of gastric acid secretion stimulated by tetragastrin in Heihenhein pouch dogs.
