Action of tyrosinase on hydroquinone in the presence of catalytic amounts of o-diphenol. A kinetic study

The formation of hydroxyhydroquinone during the action of tyrosinase on hydroquinone is demonstrated for the first time by means of high performance liquid chromatography mass spectrometry. A kinetic mechanism is proposed to explain this action in the presence of catalytic amounts of 4- tert -butylc...

Description
Summary:The formation of hydroxyhydroquinone during the action of tyrosinase on hydroquinone is demonstrated for the first time by means of high performance liquid chromatography mass spectrometry. A kinetic mechanism is proposed to explain this action in the presence of catalytic amounts of 4- tert -butylcatechol. Based on a kinetic analysis of this mechanism, an experimental design is proposed that permits the system to be characterized kinetically.
