Abstract

FLAVIN has an appreciable affinity for metal ions at physiological pH values only in its radical (semiquinoid) state. Thus in the presence of some valence stable divalent metal ions (Zn2+, Cd2+) in partially reduced flavin solutions, radical metal ion chelates which have characteristic light and electron spin resonance (ESR) absorptions1–3 are formed. We have therefore studied these chelates in some detail by means of ESR spectroscopy.
