The effect of metal ions on the reaction of hydrogen peroxide with Kraft lignin model compounds
Peroxide bleaching is significantly affected by transition and alkaline earth metals. Isolating the effects of different transition and alkaline earth metals on the reactions of peroxide with different representative lignin structures allows the separation of the positive from the negative contributions of these metal ions. In this work, five monomeric or dimeric phenolic lignin model compounds...
متن کاملThe reaction of ferrous horseradish peroxidase with hydrogen peroxide.
Hydrogen peroxide reacts with ferrous horseradish peroxidase and converts it to oxyperoxidase in a sequence of two reactions. The first is the reaction of ferrous peroxidase with HzOz to form Compound II; the second is the reaction of Compound II with HzOz to form oxyperoxidase. Both reactions follow second order kinetics, being first order with respect to each of the reactants. They proceed wi...
متن کاملSome problems on the leuco-dye-peroxide reaction. The 31st report of histochemical study of peroxidase.
In general, for the histochemical demonstration of peroxidase , b enzidine, naphthol, and leuco-dyes are utilized in the prosence of hydrogen peroxide. Among these , the technical modifications of the benzidine-peroxide method are the most numerous . Alpha-naphthol has been used less often than benzidine . Application of the leucodye method for animal tissues is remarkably limited and this meth...
متن کاملHydrogen Peroxide Adsorption on Graphene with Stone-Wales Defect
To explore the possibility of using graphene based biosensor, adsorption of hydrogen peroxide on graphene has been investigated using density functional theory. The electronic properties of defect free and defective graphene in the presence of different number of hydrogen peroxide have been studied. The graphene with the most stable configuration defect named as SW defect is considered. The hig...
متن کاملReaction of Thiol Compounds with Peroxidase and Hydrogen Peroxide*
Recent studies have indicated that peroxidase might function in the biological synthesis of thyroxine by the thyroid gland. Johnson and Tewkesbury (1) believed that thyroxine might be formed by the oxidative coupling of 2 molecules of diiodotyrosine. Westerfeld and Lowe (2) studied the oxidative condensation of p-cresol by hydrogen peroxide and peroxidase and suggested that peroxidase might be ...
