although glucose-induced ir-gip responses were not inhibited by the amino acids ( 1 g/kg ) tested , increasing concentrations ( up to 1 g/kg ) of either alanine or arginine caused progressive inhibition of corn-oil-stimulated ir-gip responses , in spite of the expected amino-acid-induced rises in insulin concentrations .
