Dependence of hydroperoxide formation as a function of (a) tyrosine; (b) acetaldehyde; or (c) arginine concentrations (0–1.0 mM) at constant horseradish peroxidase (HPO) (10 µg/mL), xanthine oxidase (XO) (0.05 U/mL), and catalase (20 µg/mL) concentrations. Hydroperoxide concentration was analyzed using FOX assay. All data were corrected relative to the peroxide equivalent calculated in the absence of amino acid. Plots are means ± SD. See general experimental section for details.
