| Abstract: | The Mossbauer spectra (from 78K to 180K) and oxygen affinity of Hb Queens and Hb Guangzhou-Hangzhou were measured.It was found that the order of magnitude of oxygen affinity was as follow; HbQueens>HbGH>HbA.The result: calculated from Mossbauer spectra showed that the distance (b) from Fe2+ to the heme plane was in the following order: HbQueens < HbGH < HbA.It showed that the smaller was the b value of the Hb, the greater was the oxygen affinity. |
