in order to assess the possible role of l-arginine accumulation in islet cells as a determinant of its insulinotropic action , the uptake of l-arginine and other cationic amino acids ( l-ornithine , l-homoarginine , d , l-alpha-methylornithine , d , l-alpha-difluoromethylornithine ) by rat pancreatic islets was compared to the ionic and secretory responses of the islets to the same amino acids .
