OXIDATION OF ADRENALINE IN ALKALINE SOLUTION

Electrocatalytic Oxidation of Glucose at Gold Nanoparticle-modified PFC electrodes in an Alkaline Solution

The electrocatalytic oxidation of glucose at Au nanoparticle-modified PFC electrodes has been studied using voltammetry technique in a (5 mM glucose + 0.1 M NaOH) solution. The PFC electrode didn't show any activity in the potential of interest (i.e. −0.8 V to 0.8 V). However, a very interesting positive catalytic effect was observed upon modification of the electrode surface with gold nanopart...

Mechanism of the catalytic oxidation of adrenaline by ferritin.

The oxidation of adrenaline to the N-methylindolequinone, adrenochrome, is catalyzed by ferritin iron in the presence of Hz02 at acid pH (1). The mechanism of this reaction, which involves the intermediate formation of hydroxyl radicals and which does not require molecular oxygen, differs from that involved at neutral or slightly alkaline pH. Our present studies show that ferritin contains a po...

Chemistry of +1 Iodine in Alkaline Solution

Cclxviii. the Oxidation of Adrenaline and Other Amines

MAMMALIAN liver and other organs contain an enzyme which catalyses the oxidation of adrenaline. By testing the ability of this enzyme to oxidize other amines of similar constitution it was found that certain groups in the adrenaline molecule, namely (a) the hydroxyl group in the side chain, (b) the phenolic hydroxyl groups and (c) the N-methyl group, were not essential for the oxidation to take...

AN NMR STUDY OF IONIC SOLVATION OF ALKALINE EARTH CATIONS WITH DIMETHYLSULFOXIDE IN NITROMETHANE SOLUTION

A proton NMR method for the determination of the solvation numbers of alkaline earth cations with dimethylsulfoxide (DMSO) in nitromethane as diluent is described. The method is based on the monitoring of the resonance frequency of DMSO protons as a function of DMSO to metal ion mole ratio while keeping the metal ion concentration constant. The average solvation number of cations at any...
