Abstract

Glutathione and its diethyl ester complexes (1 : 1) with trimethylamine N-oxide (TMAO) were studied by FTIR and 1H NMR spectrocopy. Immediately after mixing, complexes with strong SH⋯ON ⇌ S−⋯H+ON hydrogen bonds are formed. They show large proton polarizability due to the fluctuation of the proton within these bonds. These complexes are, however, not stable since disulphide bonds are formed. Thus, TMAO regulates the disulphide bond formation in glutathione systems.
