| Polarographische Untersuchungen zur Bestimmung der Stabilität von Metall-Protein-Bindungen Polarographie Investigations for the Determination of the Stability of Metal-Protein Bonds  | | | | Abstract
| Bonds betw een metals (especially copper) and a protein fraction (18,100 g/m ol) of a soya bean flour extract have been investigated. The binding capacity (304 nmol Cu/mg protein) and the binding stability (K = 1,046 • 103 in an amm onia buffer system) were determined by polarographic investigations. Changes in the polarogram caused by spiking the protein with metal ions were compared with effects in m odel substances. C ysteine, ethylenediam ine, oxalic acid and deriva tives o f benzoic acid were used as chelating agents. The effects o f functional groups on the metal-protein bonds were estim ated by the determ ination o f their different binding stabilities. | | | |
