1: a crystallizable proteolytic enzyme that differs from pepsin in several ways (as in being most active in a slightly alkaline medium and in hydrolyzing esters as well as amides) and that is produced and secreted in the pancreatic juice in the form of inactive trypsinogen and activated in the intestine—compare chymotrypsin
2: a preparation from the pancreatic juice differing from pancreatin in containing principally proteolytic enzymes and used chiefly as a digestive and lytic agent
