The angle of rotation about the blank bond is referred to as ϕ (phi) and that about the blank bond is called ψ (psi).These angles describe the blank conformation of any particular residue in any protein, and allow one to predict whether a combination of amino acids in a polypeptide will be able to form and maintain blank. conformation of any particular residue in any protein, and allow one to predict whether a combination of amino acids in a polypeptide will be able to form and maintain blank.Proline is not able to blank the ideal ϕ and ψ angles for an α helix, owing to the presence of the rigid imidic group as its side chain.Furthermore, proline does not have an blank that acts as a stabilizing blank in the middle of the helix. As a consequence, the secondary structure is predicted to be blank..
