A model peptide,TDK,was studied by circular dichroism to elucidate the effect of organic solvent on α-helical formation.The α-helicities enhanced by various alcohol solvents,especially fluorine-substituted alcohols were systematically compared.The relations between α-helical formation of a peptide and external environment were also discussed in detail.These environmental elements mainly include hydrophobicity dielectric constant and acidity of the solvents.
