Findings
Complex pseudophase diagrams depend on solvent and temperature.
Free-energy minima explain conformational behavior.
Adsorption properties significantly influence peptide conformations.
Abstract
The qualitative solvent- and temperature-dependent conformational behavior of a peptide in the proximity of solid substrates with different adsorption properties is investigated by means of a simple lattice model. The resulting pseudophase diagrams exhibit a complex structure, which can be understood by analysing the minima of the free-energy landscape in dependence of appropriate system parameters.
