L-(-)-ascorbate mobilizes iron from horse-spleen ferritin in the presence of oxygen at pH 8.0. The reaction is strongly stimulated by Cu2+. Dehydroascorbate and other stable oxidation products of ascorbate are ineffective. We present evidence that monodehydroascorbate mobilizes ferritin iron by reduction.
