gastrins


gas·trins

(gas'trinz), Hormones secreted in the pyloric-antral mucosa of the mammalian stomach that stimulate secretion of HCl by the parietal cells of the gastric glands; there are three main types: big gastrin (34 aminoacyl residues), little gastrin (17 residues), and minigastrin (14 residues), as well as sulfated derivatives. The C-terminal pentapeptide is also seen in cholecystokinin and cerulein. [G. gastēr, stomach, + -in]

(gas'trinz) Hormones secreted in the pyloric-antral mucosa of the mammalian stomach that stimulate secretion of HCl by the parietal cells of the gastric glands; a competitive inhibitor of gastrins is cholecystokinin. [G. gastēr, stomach, + -in]
