Abstract
The reaction of reducing agents with Fe(III) myoglobin fluoride from sperm whale was studied at alkaline pH values. The rate of reduction by dithionite was indistinguishable from the rate of ligand dissociation even when the values of the rate constants for both were only 1.0 X 10(-3)S-1 (at pH 10.6). Reduction by the reduced Methyl Viologen radical ion and reduced Safranine was faster than the rate of dissociation, providing evidence that these reductants can donate electrons to the iron centre via a pathway involving an (undetectable) liganded Fe(II) intermediate.
摘要
在碱性pH值条件下，研究了还原剂与抹香鲸肌红蛋白氟化物中铁（III）的反应。连二亚硫酸盐的还原速率与配体解离速率难以区分，即使两者的速率常数仅为1.0×10⁻³ s⁻¹（在pH 10.6时）。还原型甲基紫精自由基离子和还原型番红花红的还原速度比解离速度快，这表明这些还原剂可以通过涉及（不可检测的）配位铁（II）中间体的途径将电子给予铁中心。
