Claim: Helix–coil transition model include the Zimm-Bragg model that describes heliz-coil transitions of marcomolecules, usually polymer cains.
Evidence: Helix–coil transition models are formalized techniques in statistical mechanics developed to describe conformations of linear polymers in solution. Common transition models include the Zimm–Bragg model and the Lifson–Roig model, and their extensions and variations. In statistical mechanics, the Zimm–Bragg model is a helix-coil transition model that describes helix-coil transitions of macromolecules, usually polymer chains.
