| Abstract: | Horseradish peroxidase catalysed the oxidative decarboxylation of vanillic acid to methoxy-p-hydroquinone and subsequent oxidation of the hydroquinone to methoxy-p-benzoquinone. Peroxidase also catalysed the oxidation of vanillyl alcohol to vanillin and vanillic acid; however, neither vanillyl alcohol nor vanillin appeared to give rise to methoxyhydroquinone directly. Correspondingly, peroxidase catalysed the oxidative decarboxylation of syringic acid to 2,6-dimethoxy-p-hydroquinone and subsequent oxidation of the hydroquinone to 2,6-dimethoxy-p-benzoquinone. |
