摘要: The binding of Cu and Cd ions with ovalbumin has been measured indirectly by observing the displacement H+ from acidic groups on ovalbumin. pH-measuring procedure agreed values obtained an equilibrium dialysis method. Both metals were bound carboxyl log K being 2.39 2.22, respectively. extent was found to be pH dependent involvement imidazole site yielding logK 3.23 2.80, Equilibrium results supported both protein in metal ion binding.
