These left-and right-handed folded structures are energetically degenerate states and should, with proper sampling, populate equally. For example, in the 1b1s model, when side chain angles are kept symmetric about their corresponding backbone bead (θ S = 180 -θ B ) and torsions are freely rotation, the model is achiral and is expected to have degenerate left-and right-handed minimum energy structures. All molecular visualizations of CG models in this work were generated using PyMOL 2.5.
