Kinetics and Thermodynamics of the Mediator Function of 9,10-Anthraquinone Derivatives in Electrochemical Reactions with Peroxidase

摘要

On the basis of the results of studying bioelectrocatalysis induced by electrochemical reduction of N-(9,10-anthraquinon-l-and-2-yl)oxamides under conditions close to physiological in the presence of peroxidase,new criteria for estimation of the cholate-cholesterol coefficient of these compounds have been proposed;these are the rate constants for homogeneous electron transfer from the reduced form of the quinone to the active center of peroxidase and thermodynamic parameters of the process.
