In this work we are trying to gain an insight on the molecular mechanisms of the salt effects on conformational stability of proteins with use of fully atomistic Molecular Dynamics simulations techniques. Such ‘in silico’ approach allows us to obtain quite realistic data on the time and scale resolutions that are unavailable for both ‘in vitro’ and ‘in vivo’ experimental techniques. We investigated a trialanine peptide which is the one of the simplest examples of biomolecules, bearing the essential features of proteins.
