Studies of reactions between flavins and quinones, mercaptans, and enolates.
A. Equilibrium and second-order rate constants have been measured for the redox reaction between phthaloquinone and dihydroriboflavin (and its reverse) at a number of pH values. The equilibria and kinetic determinations are in agreement. No intermediates could be found in the reaction, and it is proposed that with this and other quinones electron transfer occurs within a complex of the flavin a...
متن کاملImpregnated Carbons for the Adsorption of H2s and Mercaptans
Activated carbon has been used for many years for the adsorption of H2S and Mercaptans from natural gas streams, carbon dioxide, and sewage vents. It is widely thought that the carbon pore surface catalyses the oxidation of HzS to elemental sulfur and higher oxidized forms of su l fd2 . However, due to the poor loading capacities achieved at ambient conditions, most commercial activated carbon ...
متن کاملREACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).
متن کاملBlood and brain concentrations of mercaptans in hepatic and methanethiol induced coma.
It has been suggested that mercaptans are important factors in the pathogenesis of hepatic encephalopathy. Using a gas liquid chromatographic technique which uses propanethiol as internal standard and a sulphur specific detector, blood methanethiol concentration was found to be significantly risen in encephalopathic patients with liver disease (13.2 +/- 1.0 nmol/ml; n = 47) compared with contro...
