Chymotrypsin is a digestive enzyme that hydrolyzes proteins in the small intestine. The pre-cursor of Chymotrpsin with 25,000 Dalton molecular weight. It belongs to serine protease. It is purified by re-crystallization, and showing one lane in electrophoresis.
Chymotrypsin is a white or almose white lyophilized powder. Its inactive precursor, chymotrypsinogen, is synthesized in the pancreas, as are several other zymogens and digestive enzymes. Actually, the pancreas is one of the most active organs in the synthesizing and secreting proteins. The enzymes and zymogens are synthesized in the acinar cells of the pancreas and stored inside membrane-bounded granules. The zymogen granules accumulate at the apex of the acinar cell; when the cell is stimulated by a hormonal signal or a nerve impulse, the contents of the granules are released into a duct leading into the duodenum.
