以标准方式制备的硫肌红蛋白的质子核磁共振谱揭示了具有不同化学反应性的三种形式A、B和C的存在。给出了这些形式相互转换的条件。不同晶型的~ 1H NMR谱图显示相似的模式。似乎形式之间的差异涉及卟啉外围的化学修饰。改变的血红素可以从Fe III（CN）硫肌红蛋白C中提取，得到稳定的绿色物质。
The proton nuclear magnetic resonance spectrum of sulfmyoglobin prepared in standard fashion reveals the presence of three forms, A, B, and C, with different chemical reactivity. Conditions for some interconversions of these forms are given. The1H NMR spectra of the different forms show similar patterns. It appears that the differences between forms involve chemical modification on the porphyrin periphery. The altered heme can be extracted from FeIII(CN)sulfmyoglobin C to give a stable green substance.
