| pubmed-article:1032246 | pubmed:abstractText | 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. | lld:pubmed |
