Clxx. the Oxidation of Sulphydryl Compounds by Hydrogen Peroxide. I. Catalysis of Oxidation of Cysteine and Glutathione by Iron
THE oxidation of thiol compounds by oxygen and methylene blue has, in recent years, been very extensively studied, while their oxidation by hydrogen peroxide has suffered almost complete neglect. Abderhalden and Wertheimer [1923] found that cysteine, like other mercaptans, was instantaneously oxidised by hydrogen peroxide in neutral solution, and that this oxidation was unaffected by cyanide. A...
متن کاملThe Rate of Oxidation of Iodide Ion by Hydrogen Peroxide
T HE practice of chemistry is concerned very largely with the carrying out of chemical reactions whereby new substances are produced from old. The substances entering into the reaction are'known as reagents, and the substances produced as products. One of the factors in chemical reactions which is subject to human control and manipulation is summarized in the Law of Mass Action. This law, in si...
متن کاملThe Oxidation of Sodium Lactate by Hydrogen Peroxide
By means of a modification of the technique of the Osterhout apparatus it is possible to follow the production of CO(2) from sodium lactate when acted upon by H(2)O(2). The results of this process indicate that the reaction is not a simple one but is of an autocatalytic type. This conclusion is borne out by the fact that the determinations of H(2)O(2) during the reaction show an increased amoun...
متن کاملSelective oxidation reactions of natural compounds with hydrogen peroxide mediated by methyltrioxorhenium.
We have investigated the oxidative behaviour of natural compounds such as methyl abietate (1), farnesyl acetate (2), α-ionone (3), β-ionone (4), methyl linolelaidate (5), methyl linolenate (6) and bergamottin (7) with the oxidant system methyltrioxo-rhenium/ H2O2/pyridine. The reactions, performed in CH2Cl2/H2O at 25 °C, have shown good regio- and stereoselectivity. The oxidation products were ...
متن کاملSelective oxidation of sulfides to sulfoxides by a vanadium-based catalyst using 30% hydrogen peroxide
The vanadium-based catalyst, acts as a homogeneous catalyst for the selective oxidation of various kinds of sulfides with 30% aqueous H2O2. Vanadium-based catalyst was successfully used as the oxygen source for the oxidation of sulfides to sulfoxides for the first time. The sulfoxides were obtained in a good way to high yields without any detectable over-oxidation to sulfones under normal condi...
