摘要：

The spectral changes of nitrosyl Hb on addition of inositol hexaphosphate were studied in hybrid-heme Hb [human]. The decrease in absorption in the Soret region was mainly due to a spectral change in .alpha. chains, and that the tension on heme in the quaternary T structure was much stronger in .alpha. than in .beta. chains.
