Metabolism of the gastrointestinal peptide hormones.
Results of investigations on the metabolism of gastrin, pentagastrin, cholecystokinin and secretin are discussed on the basis of data in the literature. Own results concerning the metabolism of 14C-pentagastrin are also described, out of which the significance of a biologically inactive metabolite is emphasized. This metabolite can be demonstrated in the circulation, and is excreted in the urine. As judged from the present state of investigations, this metabolite has a crucial importance in the metabolism of pentagastrin.
