The chemical reactivity of various alpha-keto acid anions (beta-hydroxypyruvate, beta-phenylpyruvate, 2-ketobutyrate and 2-ketoglutarate) with hydrogen peroxide (H2O2) was investigated at physiological pH (7.4) and a temperature of 25 degrees C. The initial concentration of the alpha-keto acid anions was kept
