title: [Heme structure in cooperative and noncooperative hemoglobins: study by resonant Raman diffusion].
abstract: The modifications of heme sites of hemoglobin, which should occur upon apoprotein alterations (responsible for variations of oxygen affinity), have been examined by Resonnant Raman scattering. The oxygenated (R) and deoxygenated (T) shape of apoprotein do not modify the heme states. The spectral differences between these forms are essentially due to the presence or the absence of the sixth ligand.
