Message: | 1.Secretin acetate is a hormone that is responsible for controlling the environment of a duodenum by regulating pancreatic and stomach secretions while regulating the water homeostasis throughout an animal's body. Specifically, it helps to regulate the duodenum's pH by inhibiting the secretion of gastric acid from the parietal cells of the stomach and increasing stimulation of the bicarbonate production in the centroacinar cells from the pancreas.
2.The first species was found in animal hormone. As a basic polypeptide. Composed of 27 amino acid residues, containing 11 kinds of amino acids. Bayless and Starling (Bayliss and Starling) is equal to the discovery in 1902.
