the contribution of amino acids other than glutamine to renal ammoniagenesis was investigated in renal tubules obtained from control rats and rats with metabolic acidosis by incubating 2.5 mm [ 5-15n ] glutamine , [ 2-15n ] glutamine , [ 15n ] glutamate , [ 15n ] aspartate , [ 15n ] alanine , or [ 15n ] glycine , either as the sole n source in krebs bicarbonate buffer or as a labeled substrate in a medium containing a mixture of unlabeled amino acids .
