Question

Quizplus · Accepted Answer

Ramachandran determined the allowed values of the phi and psi angles by considering steric hindrance, which dictates the physical feasibility of certain conformations. The pKa values of the amino acids, the hydropathy of amino acids, and hydrogen bonding effects are not directly related to the allowed values of phi and psi angles.
