About

• A Ramachandran plot is a way to examine the backbone conformation of each residue in a protein.
• It was first used by noted Indian biophysicist G.N. Ramachandran in 1963 to describe stable arrangements of individual residues of a protein. Today, a Ramachandran plot is frequently used by crystallographers to identify protein models with an unrealistic backbone.
• Ramachandran plot is used to examine and assess any structure in peptides.
• Peptides are short chains of amino acids linked by peptide (amide) bonds.
