A comparison between the ease of haemoglobin oxidation and modification by sulphide.
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.
