Abstract:
Tropolone (2,4,6-cycloheptatrien-1-one), in the presence of hydrogen peroxide but not in its absence, can serve as a donor for the horseradish peroxidase catalysed reaction. The product formed is yellow and is characterized by a new peak at 418 nm. The relationship between the rate of oxidation of tropolone (ΔA at 418 nm/min) and various concentrations of horseradish peroxidase, tropolone and hydrogen peroxide is described. The yellow product obtained by the oxidation of tropolone by horseradish peroxidase in the presence of hydrogen peroxide was purified by chromatography on Sephadex G-10 and its spectral properties at different pHs are presented. The M, of the yellow product was estimated to be ca 500, suggesting that tropolone, in the presence of horseradish peroxidase and hydrogen peroxide is converted to a tetratropolone. © 1985.
