A Ramachandran Plot illustrates acceptable phi (φ) and psi (ψ) angles for amino acids in a polypeptide. What is the primary factor that restricts these angles? The relative abundance of proline. a The degree of side chain (R-group) interactions. b The relative amount of inter- and intra-strand hydrogen bonding. c Solvent entropy (hydrophobic effect) d Steric hindrance.
