Dielectric dispersion in myoglobin solution

Abstract

Myoglobin, the red pigment of muscle tissue, exhibits in aqueous solution two major regions of dielectric dispersion [1-3]. Between these a much smaller dispersion has been inferred to exist [3,9]. The three, denoted β,δ,γ, are considered to arise from reorientation of protein, bound water, and solvent water respectively [1]. Herein are described further efforts to characterize the δ dispersion and to choose an appropriate model to represent the experimental results.
