Abstract:
This study was aimed to understand which substitution position of hydroxy groups on benzene ring is the most suitable for active site of enzyme tyrosinase, and also to determine if
tyrosinase is a useful biological component for the development a biosensor based on carbon
material for the determination of polyphenolic compounds in food samples. Electrochemical
properties of diphenols (catechol, resorcinol, and hydroquinone) at bare carbon paste electrode
(CPE) and CPE surface-modified with conductive copolymer Nafion and enzyme mushroom tyrosinase (CPE/Tyr/Nafion) were investigated using cyclic voltammetry and hydrodynamic amperometry.
