Why the different visual colors of Hb in the various redox and ligand states? Explain why the reduced globin spectra of Hb appears heterogeneous or as a mixture of forms.

Solution

Different visual colors of Hb due to oxidation state of iron (II) tends to exist in a high spin 3d⁶ configuration with 4 unpaired electrons, another state of iron (III) has 3d⁵ odd number of electrons, and thus must have one or more unpaired , in any energy state.   Binding of oxygen to molecule placed high-spin iron (II) in an octahedral field of strong field ligands; this change field would increase the crystal field splitting energy causing iron electrons to pair into low spin configuration, which would be diamagnetic in Fe(II).

Hb is redox active especially released from reducing enviornment of erythrocytes during normal and abberrent hemolysis

reduced globin spectra of Hb appears heterogeneous because of mutations
