摘要

Hemoglobin (Hb) of normal erythrocytes undergoes oxidative reactions with constant rate. In anemia, hemoglobin is exposed to oxidative denaturation. Oxidation of oxy-hemoglobin gives O–2 and met-hemoglobin (met-Hb). If the globin structure of hemoglobin molecule is destabilized, met-hemoglobin can be converted to hemichrome. Reaction of hemoglobin with radical or oxidant-generating system and structure denaturation can be followed by spectral analysis. In this study, different oxidation products of hemoglobin were measured in three types of anemia; sever iron deficiency, glucose-6-phosphate dehydrogenase deficiency and β-thalassemia. The results showed that hemoglobin suffers from an increase in the auto-oxidation rate in case of anemia followed by an enhancement in both met-hemoglobin and hemichrome levels and a decrease in the oxy-hemoglobin concentration
