Proteins are polymers of amino acids that can exist in ordered structures stabilized by a variety of molecular interactions. However, when certain conditions are changed, the compact structure of a polypeptide chain may collapse into a random coil. This structural change may be regarded as a phase transition occurring at a characteristic transition temperature, the melting temperature, Tm, which increases with the strength and number of intermolecular interactions in the chain. A thermodynamic treatment allows predictions to be made of...
