Selective pancreatic enzyme secretion due to a new peptide called chymodenin

Science. 1974 Mar 15;183(4129):1087-9. doi: 10.1126/science.183.4129.1087.

Abstract

Chymodenin, a peptide newly isolated from porcine duodenum, elicited a rapid threefold increase in secretion of chymotrypsinogen while increasing secrelion of total protein by only, about 40 percent; lipase secretion was unaffected. The pancreas appears able, under chymodenin stimulation, to rapidly alter the transport of an individual enzyme as opposed to producing en masse secretion of enzyme.
