    Abstract

    The response of a random heteropolymer to preferential solvation at the globule-solvent interfaces was investigated. For each set of monomers, the ensemble of allowed configurations was represented by a Gaussian distribution of energy levels. It was found that mean surface composition is proportional to the solvation strength. It was also found that fluctuations play a crucial role in determining the excess of solvophilic monomers at the surface.
