Expert Solution
Step 1

The Ramachandran plot is a plot of the torsional angles - phi (φ)and psi (ψ) - of the residues (amino acids) contained in a peptide. It  is a way to represent the energetically allowed regions for backbone dihedral angles ψ against φ of amino acid residues in protein structure.
