Intestinal juice (succus entericus) refers to the clear to pale yellow watery secretions from the glands lining the small intestine walls. Secretion is stimulated by the mechanical pressure of partly digested food in the intestine. Diagram showing the small intestine In biology the small intestine is the part of the gastrointestinal tract (gut) between the stomach and the large intestine. ...
Its function is to complete the process begun by pancreatic juice; the enzymetrypsin exists in pancreatic juice in the inactive form trypsinogen, it is activated by the intestinal enterokinase in intestinal juice. Trypsin can then activate other protease enzymes and catalyze the reaction pro-colipase --> colipase. Colipase is necessary, along with Bile Salts, to enable Lipase function. Pancreatic juice is a juice produced by the pancreas. ... Ribbon diagram of the enzyme TIM, surrounded by the space-filling model of the protein. ... Trypsin (EC 3. ... Trypsinogen (EC 3. ...
