Reactions of flavosemiquinone radicals in the presence of metal ions

Rate constant of disproportionation of flavosemiquinone radicals has been determined taking advantage of impulse spectroscopy. Yield of flavosemiquinone radical increases with addition of iron(II)-ammonium sulfate to riboflavin solution. Spectral-kinetic parameters of flavosemiquinone radical comple...

Description
Summary:Rate constant of disproportionation of flavosemiquinone radicals has been determined taking advantage of impulse spectroscopy. Yield of flavosemiquinone radical increases with addition of iron(II)-ammonium sulfate to riboflavin solution. Spectral-kinetic parameters of flavosemiquinone radical complexes with Zn 2+ and Cd 2+ have been obtained.
