title: [Helix-coil transitions of a polypeptide in a two-component solvent].
abstract: A microscopic model is considered of a helix-coil transition of polypeptides in a two-component solvent one of whose components competes for the formation of hydrogen bonds with the peptide group. It is shown that by a redetermination of the temperature parameter the model is reduced to a polypeptide chain without the solvent. Behavior of the transition parameters is calculated in relation to the solvent concentration competing for the formation of hydrogen bonds at different parameters of polypeptide-solvent interaction.
