摘要：

The interaction between the VO2+ cation and cystine was investigated by electron absorption spectroscopy in aqueous solutions at different metal-to-ligand ratios. Reduction of NaVO3 solutions with cysteine gave similar spectra. The results suggest that interaction occurs through the carboxylate and amino groups of the ligand. The interest of the results in relation to vanadium metabolism are commented upon.
