A molecular model of gastrin, a peptide hormone released by G cells in the stomach, duodenum and pancreas, responsible for stimulating the secretion of gastric acid and aiding in gastric motility. Gastrin is released in response to an enlargement of the stomach, the presence of partially digested proteins, hypercalcemia or stimulation from the vagus nerve. Atoms are colored dark gray (carbon), light gray (hydrogen), red (oxygen), blue (nitrogen) and yellow (sulphur).
