WebFlavins exist in three redox states: oxidized, semiquinone (1 e − reduced, radical), and hydroquinone (2 e − reduced, fully reduced). Six out of the nine possible redox/ionic forms are physiologically relevant based on their pK a values (Fig. 2), with each form displaying a characteristic UV-visible absorbance spectrum.In solution flavin semiquinones and …

WebDec 11, 2024 · The flavin as electron acceptor was placed at the N-terminus and two Trps with 0–3 intervening prolines to direct the ET. Spectroscopic studies, especially time-resolved investigations, demonstrated how the number of prolines and thereby the distance between flavin and Trp moieties affect excited state lifetimes as well as the quantum yields. In biochemistry, flavin adenine dinucleotide (FAD) is a redox-active coenzyme associated with various proteins, which is involved with several enzymatic reactions in metabolism. A flavoprotein is a protein that contains a flavin group, which may be in the form of FAD or flavin mononucleotide (FMN). Many flavoproteins are known: components of the succinate dehydrogenase complex, α …
