[Oxygen-binding properties of human hemoglobin solutions UV-irradiated in the presence of iodoacetamide].
Changes of oxygen-binding properties of human hemoglobin solutions modified by the different concentrations of iodoacetamide and by this chemical agent together with UV-light in doses 151 and 755 J/m2 has been studied by means of spectroscopy. It has been shown that addition of iodoacetamide to native hemoglobin solution (12:1) results in increase of the oxygen affinity and breach of the hem-hem interaction of hemoprotein. It has been ascertained that influence of UV-radiation on hemoglobin displays in photodissociation of the tetramers to protomers.
