established by X-ray crystallographic analysis. Selenenyl sulfides obtained by the reaction of the selenenic acid with 1,4-dithiols were reduced
to the corresponding selenol by treatment with a tertiary amine, thus achieving the experimental demonstration of three processes included
in the catalytic cycle of glutathione peroxidase.
