- 論文の詳細を見る
The electrochemical redox reaction of flavin mononucleotide (FMN) adsorbed on a hanging mercury drop electrode was studied in a pH 6.9 phosphate buffer and a pH 4.9 acetate buffer by means of cyclic d.c. and phasese lective a.c. voltammetry. Both the oxidized and reduced forms of FMN arc strongly adsorbed on the electrode surface, and a stable adsorption layer of FMN((FMN)<SUB>ad</SUB>) is formed. The cyclic d.c. and a.c. voltammetric behavior of (FMN)<SUB>ad</SUB> is explained by equations for a two-step one-electron surface redox reaction. The formal standard redox potentials, semiquinone formation constants, and charge transfer-rate constants of the surface redox reaction of FMN at the mercury electrode were determined.
