A mechanism of the formation of an aldehyde in the reaction between formic and carboxylic acid has been proposed. It is assumed that a mixed formic-carboxylic anhydride is formed with its subsequent decarboxylation to an aldehyde. On the basis of XRD measurements of freshly prepared manganese ...
The reactivity of the acids studied towards Ce(IV.) increased in the following order, acetic < glycine <glycollic attributed to their chelating power. Activation parameters were evaluated and a mechanism was suggested which involves intermediate complex formation between Ce(IV) and the monocarboxylic ...
Dehydromethionine (S-methylisothiazolidine-3-carboxylic acid) is reduced by glutathione (aqueous solution, 25°C) to give methionine and glutathione disulfide in a reaction that is dependent on pH and the nature and concentration of the buffer utilized. The data are consistent with proton-assisted...
A detailed inspection of the substrate pocket suggested the neighboring Cys26 blocking direct access of 1a to Tyr28 (Supplementary Fig. 1). The long distance between the Cys-SH and the alkene Cα renders an involvement of Cys26 as proton source in the catalytic mechanism unlikely. Thus, we ...
hydroxy carboxylic acidsThe reaction of Np(VI) with organic acid anions in solutions containing lithium salts of tartaric, malic, 伪-aminoglutaric, and trihydroxyglutaric acids was studied. Changes in the solution spectra show that Np(VI) forms complexes with organic acid anions, which is followed...
