In peptides the values of dihedral angle phi (D) is based on rotation around

In peptides the values of dihedral angle phi (D) is based on rotation around (1) N-Ca bond (2) Ca -C’ bond (3) C’-N bond (4) N-H bond The phi (φ) angle in peptides is defined as the dihedral angle around the N–Cα bond. This angle is measured between the plane formed by the C’ (of … Read more
