Abstract

Abstract: The interactions between Co(Ⅱ) ion and HSAor BSAwere studied by means of charge transfer spectra. Both Co(Ⅱ) and Co(Ⅲ) have been found at the binding sites of albumin. The coordination environment of Co(Ⅱ) and Co(Ⅲ) are likely to be identical, which are octahedral type involving α-amino and carboxyl. So these ions are likely to locate at the N-terminal of albumin.

Key words: Charge transfer spectra, Optical electronegativity, Serum albumin, Cobalt
