Phi and psi angles amino acids

Web4. sep 2024 · Each amino acid contains two bonds that can readily rotate – this includes the phi angle and the psi angle. The phi angle is the angle between the alpha carbon atom and the nitrogen while the psi angle is the angle between the alpha carbon and the carbon of the carbonyl group.
