Oxidation of ammonia and hydroxylamine to nitrate in the rat.


We have demonstrated that ammonia is oxidized to nitrate in the rat. Male Sprague-Dawley rats gavaged with 1 000 mumol 15N-ammonium chloride each day for five days were found to excrete low, but significant, amounts of excess 15N-nitrate in their urines on the five days of treatment and on the five subsequent days. We recovered a total of 0.28 +/- 0.03… (More)
