This paper presents a computational study on helix folding and unfolding of length 10 homopeptides composed of the nonpolar amino acids methionine, alanine, leucine, phenylalanine, isoleucine, valine and glycine. We apply a Monte Carlo Simulated Annealing (MCSA) framework to derive energetic parameters which allow to differentiate between α-helix formers and helix breakers within this group of peptides,...
