Helix-coil transitions of homo-oligomers in aqueous solution are studied by multicanonical Monte Carlo simulations. The solvation effects are represented by the term that is proportional to the solvent-accessible surface area of the peptides. Homo-oligomers of length 10 are considered for two characteristic amino acids, alanine and glycine, which are helix former and helix breaker, respectively. It is shown that the helix-coil transition temperature for homo-alanine in water is considerably lower than in gas phase. The helix propagation parameter s and nucleation parameter σ for both alanine and glycine are calculated and shown to be in remarkable agreement with experimental results.
