Microwave Dielectric Response of Water in Solutions of Hemoglobin in Different States

In this work, dielectric response of water in solutions of hemoglobin (Hb) in its different states (MetHb, OxyHb and DeoxyHb) is considered. Dielectric response is interpreted in a unified manner by considering α(lnτ) dependence. It was shown that hydration of the protein is characterized by a mixed type of interaction. Moreover, a transition from a dipole-ion type of interaction to a dipole-dipole one occurs.
