The Ramachandran plot is a plot of the torsional angles - phi (φ)and psi (ψ) - of the residues (amino acids) contained in a peptide. ... By making a Ramachandran plot, protein structural scientists can determine which torsional angles are permitted and can obtain insight into the structure of peptides.

Ramachandran plot is used to confirm the structure of PROTEINS.
Ramachandran plot:
- A Ramachandran map, first devised in 1963 by G. N. Ramachandran, C. Ramakrishnan, and V. Sasisekharan, is a method in biochemistry for visualizing energetically permissible regions for backbone dihedral angles ψ against φ of amino acid residues in protein structure.
- The Ramachandran plot is a visualization of the torsional angles - phi (φ) and psi (ψ) - of the peptide residues (amino acids).
- Ramachandran is used to measuring angles in amino acids (proteins), but the technique can be applied to other types of molecules as well.
- The Ramachandran plot does not apply to lycine and proline.
- Because it has a hydrogen atom as its R group, glycine is a very simple amino acid.
Structure of proteins:
- The linear sequence of amino acids in a peptide or protein is known as its primary structure.
- The main structure of a protein is typically given from the amino terminus to the carboxyl terminus.
- Ribosomes are the most prevalent protein biosynthesis enzymes found in cells.
