Urea (about 5 mol l-1) causes an approximately five-fold increase of the dielectric increment of bovine serum albumin at 20 degrees C. The increase is reversed by betaine (about 2.5 mol l-1), or prevented if urea and betaine are added together. This result can be seen as an electric counterpart to the protective role of osmolytes which are secreted by cells… CONTINUE READING
