PURPOSE The objective of this study was to determine the influence of the peptide bond with emphasis on the carbonylgroup on the interaction with and transport by the intestinal small-peptide carrier. Therefore enalapril, a known substrate for the small-peptide carrier, has been modified to an analogue with a reduced peptide bond, enamipril. The transport characteristics of both compounds have been
