Nitric oxide is unique among the higher oxides of nitrogen in its reactivity and efficiency for the oxidation of oxygen-bound hemoproteins. Dinitrogen trioxide serves as a nitric oxide donor, but dinitrogen tetroxide does not exhibit similar reactivity. Details are provided of the stoichiometric transformation through which nitric oxide is converted to nitrate with accompanying oxidation of myoglobin or hemoglobin to the corresponding iron(III) hemoprotein, including an estimate of the rate… CONTINUE READING
