The ramachandran plot
WebbRamachandran plot from wikimedia based on the original plot by Ramachandran et al. Favoured, or fully allowed region, is marked with solid black lines, allowed, or outer limit region, is represented with a dotted black line. Ramachandran et al. could assign key secondary structures to specific regions in the plot. WebbEssay on the Ramachandran Plot: The peptide backbone is constrained by steric hindrance and hydrogen bonding patterns that limit its torsional angles (phi-psi angles) to certain limits. Plots of phi versus psi dihedral angles for amino acid residues are called Ramachandran plots.
