WebbThe Ramachandran plot is a plot of the torsional angles (angles between two planes) – psi (ψ) and phi (φ)– of amino acids contained in a peptide. It is used to show the ranges of angles that are permissible and the main types of structure adopted by a polypeptide chain (for example, α helix, β sheet).
