WebbThe protein backbone can be described in terms of the phi, psi and omega torsion angles of the bonds: The phi angle is the angle around the -N-CA- bond (where 'CA' is the alpha …
Webba. would have the all phi angles clustered around -60˚ b. would have all psi angle clustered around -60˚ c. would have all of both phi and psi angles clustered around -60˚ d. would show proline’s peptide bond is more stable in the cis conformation e. would be identical to those of the other amino acids because it is also an L-amino acid 3. WebbThe phi and psi values are measured for each amino acid. Each pair of phi, psi values is then mapped on to the nearest grid point. The average phi, psi value of each grid point is then calculated. For e.g., the phi,psi pairs -60.,-40 and -60,-50 would be mapped to the grid point -60,-60. The average phi, psi value is then -60, -45.

Each amino acid residue in the peptide chain therefore has one phi and one psi bond, each of which can exist in three stable bond angles. Therefore, for a 100-residue peptide, there are 198 phi and psi bonds and so 3^198 possible conformations. ios number compatible for pocket campWebbThey are the only covalent bond formed between amino acids in polypeptide structures. The angles between the participating C and N atoms are described by the values psi (psi) and phi (phi). They have partial double-bond character. All of the above.
