WebbThe least restricted phi and psi angles are found in polypeptides in which class of secondary structure? a. right-handed alpha helix b. beta sheet ... The ridges and grooves of an alpha helix form an angle of about 25 degrees or about 45 degrees to the helical axis. Webbthe phi and psi angles of the alpha helix (lie in the center of an allowed, minimum energy region of the Ramachandran (phi, psi) map. the dipoles of hydrogen bonding backbone atoms are in near perfect alignment. the radius of the helix allows for favorable van der Waals interactions across the helical axis.

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.
WebbThe ω angle at the peptide bond is normally 180°, since the partial-double-bond character keeps the peptide bond planar.
