Abstract
The haemoglobin purified from a wide range of species undergoes facile sulphaemoglobin formation as well as oxidation. Oxidation by either anions such as azide or organic electron transfer reagents shows similar facility. Facile oxidation of a particular haemoglobin is associated with protection against sulphaemoglobin formation. Oxidation and sulphaemoglobin formation in some instances occur via competing electron transfer reactions.
摘要
从多种物种中纯化得到的血红蛋白容易形成硫血红蛋白并发生氧化。由诸如叠氮化物等阴离子或有机电子转移试剂引发的氧化表现出相似的易发性。特定血红蛋白的易氧化与防止硫血红蛋白形成相关。在某些情况下，氧化和硫血红蛋白形成是通过相互竞争的电子转移反应发生的。
