people infected with diabetes (Gly-Hb 10%) and serious diabetics (Gly-Hb 15%) were investigated by Mossbauer spectyoscopy at liquid nitrogen temperature. All the experimental spectra of hemoglobin are composed of three doublets corresponding to oxy-hemoglobin (Oxy-Hb)
deoxy-hemoglobin (Deoxy-Hb) and low-spin hemochrome (Ls-Hemo) respectively. It is found that Oxy-Hb is decreasing but Deoxy-Hb increasing for diabetes. Experimental results also indicate that the line-width of Mossbauer spectra of Oxy-Hb for diabetics is narrower than that for normal adults
showing that while Fe in Oxy-Hb exists in pile-up of some similar states for normal adults
bat it becomes in single state for serious diabetes.
