Hemoglobin was the carrier of oxygen in blood circulation. For the patients with diabetes mellitus the enhencement of glycated hemoglobin in blood causes the decrease of oxygen transmission function. In this work
the local atomic structures of iron in hemoglobin were determined by EXAFS techniques. The relationship between diabetes mellitus and hemoglobin structures was observed. The blood samples were taken from normal people
slight and serious diabetic patients. The results show that the coordination number of iron atoms and Fe—O bond length were almost the same for the three samples. However
for the samples of serious diabetic patients the Fe—N bond length increases by about 0.002nm
the possible reasons were the increase of deoxyhemoglobin contents in their blood.
