对铁(III)催化氧化半胱氨酸的研究表明，该反应对半胱氨酸和氧均为零级，对铁离子为三分之二级。有一个明显的pH效应，在pH 8.1有一个明显的最大速率，铁-半胱氨酸络合物的存在已经被很好地记录下来了。对这些观察结果的定量解释导致了以下建议。
A careful investigation of the iron (III)-catalyzed oxidation of cysteine has demonstrated that the reac-tion is zero order with respect to both cysteine and oxygen but two-thirds order with ferric ion. There is a marked pH effect with a pronounced maximum in rate at pH 8.1, and the existence of an iron-cysteine complex has been well documented. A quantitative interpretation of these observations leads to the following proposal.
