Fenton chemistry. Amino acid oxidation.
The oxidation of amino acids by Fenton reagent (H2O2 + Fe(II] leads mainly to the formation of NH+4, alpha-ketoacids, CO2, oximes, and aldehydes or carboxylic acids containing one less carbon atom. Oxidation is almost completely dependent on the presence of bicarbonate ion and is stimulated by iron chelators at levels which are substoichiometric with respect to the iron concentration but is inh...
متن کاملFenton chemistry at aqueous interfaces.
In a fundamental process throughout nature, reduced iron unleashes the oxidative power of hydrogen peroxide into reactive intermediates. However, notwithstanding much work, the mechanism by which Fe(2+) catalyzes H2O2 oxidations and the identity of the participating intermediates remain controversial. Here we report the prompt formation of O=Fe(IV)Cl3(-) and chloride-bridged di-iron O=Fe(IV) · ...
متن کاملLxxvii. the Chemistry of Amino-acid Deamination
THE final phase of amino-acid metabolism, involving the removal of nitrogen from the amino-group and the production of urea, is generally regarded as involving two distinct processes: (1) deamination, with the liberation of ammonia, (2) dehydration of ammonium carbonate, with formation of urea. The change being represented as: R. CH(NH2) . COOH NH3 (NH4C03CON2H4 Now, while there is no doubt as ...
متن کاملIndicator amino acid oxidation: concept and application.
The indicator amino acid oxidation (IAAO) method is based on the concept that when 1 indispensable amino acid (IDAA) is deficient for protein synthesis, then all other IDAA, including the indicator amino acid, will be oxidized. With increasing intakes of the limiting amino acid, IAAO will decrease, reflecting increasing incorporation into protein. Once the requirement for the limiting amino aci...
متن کاملLandfill Leachate Treatment through Electro-Fenton Oxidation
Advanced Oxidation Processes (AOPs) have been employed to degrade biorefractory organic matters. This study investigates the combination of classical Fenton reaction with electrochemical oxidation, the electro-Fenton process, for the treatment of semi aerobic landfill leachate, collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. The investigation has been carried out in batch re...
