Abstract
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 and tissues subjected to various types of internal or environmental stress.Entities:
