4‐Methyl catechol and catechol, at concentrations ranging from 0.03 to 9 mM and 0.066 to 20 mM, respectively, have a synergistic effect on the rate of DL‐DOPA oxidation by mushroom tyrosinase to material absorbing at 475 nm. The synergism results from the ability of 4‐methyl catechol‐o‐quinone (4‐methyl‐o‐benzoquinone) and of catechol‐o‐quinone (o‐benzoquinone) to oxidize DL‐DOPA non‐enzymatically to dopaquinone, with the latter being immediately converted to d
