The kinetics of reactions of cobalamin (II) and cobinamide (II) with sulfur dioxide was studied by UV-visible (UV-vis) spectroscopy. Reaction results in oxidation of Co(II) center and involves two aquated SO moieties. The final product is suggested to be complex Co(III)-SO . The absence of corrin ring modifications during the reactions was proved.
通过紫外可见光谱研究了钴胺素（II）和辅酶B12（II）与二氧化硫的反应动力学。反应导致Co（II）中心氧化，涉及两个水合SO部分。最终产物被认为是配合物Co（III）-SO 。证明了反应过程中没有咕啉环修饰。
