The conformation of the backbone of a polypeptide is described completely by the angles) of rotation about which bonds)? A) the peptide bond only B) N-C_αonly C) N-C_α, C_α-C and C-N bonds D) N-C_αand C_α-C bonds only

Question

Quizplus · Accepted Answer

The conformation of a polypeptide backbone is described by the rotation angles around the N-Cα (phi, φ) and Cα-C (psi, ψ) bonds. The peptide bond (C-N) is planar and does not rotate.
