Webb29 sep. 2016 · Polypeptide main chain dihedral angles: Phi (φ), Psi (ψ), and Omega (ω) A dihedral angle is defined by four atoms. It can be visualized by looking down the central bond (i.e. the bond from atom 2 to atom 3). … WebbThe phi and psi angles for each residue in a protein are neatly summarized in a Ramachandran plot. The horizontal and vertical axis represent the phi and psi angles of a peptide residue. A single point in the plot represents the phi and psi values of one residue.
