Websecretin, a digestive hormone secreted by the wall of the upper part of the small intestine (the duodenum) that regulates gastric acid secretion and pH levels in the duodenum. Secretin is a polypeptide made up of 27 amino acids. It was discovered in 1902 by British physiologists Sir William M. Bayliss and Ernest H. Starling. WebEnzymes. Enzymes are proteins which act as catalysts to facilitate the conversion of substrates into products. Enzyme classification has been developed by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC- IUBMB ), which arranges enzymes into six large families: EC 1.-.-.-. Oxidoreductases.
Secretin primarily functions to neutralize the pH in the duodenum, allowing digestive enzymes from the pancreas (e.g., pancreatic amylase and pancreatic lipase) to function optimally. Secretin targets the pancreas; pancreatic centroacinar cells have secretin receptors in their plasma membrane.

WebTrypsin is one of the three principal digestive proteinases, the other two being pepsin and chymotrypsin. In the digestive process, trypsin acts with the other proteinases to break down dietary protein molecules to their component peptides and amino acids. Hence, trypsin acts on proteins and the end product is dipeptides. Web23 Feb 2016 · Gastrin acts on the gastric glands and stimulates the secretion of hydrochloric acid and pepsinogen. Secretin acts on the exocrine pancreas and stimulates secretion of water and bicarbonate ions. CCK acts on both pancreas and gall bladder and stimulates the secretion of pancreatic enzymes and bile juice, respectively.
WebSecretin. Secretin is a 27–amino acid peptide that is synthesized predominantly in the brain and gastrointestinal tract. In the gut, secretin is produced by the enteroendocrine S cell in the duodenum and proximal jejunum. Gastric acid, bile salts, and luminal nutrients stimulate secretin, and somatostatin inhibits its release.
