In doing this, the energies of the unfolded conformations (and thus Ec ) do not change, because they depend only on the amino acids composition, while the energy of the native conformation, which depends on the particular sequence, reaches values below Ec .

Note, however, that the very notion of an established contact itself depends on two amino acids coming closer together than some threshold value, rc , of their mutual distance.
Chirality and Protein Folding
Unless stated otherwise, the cut-off value for the presence of a contact between amino acids i and j we take 1.5σij in model proteins and 1.36σij in model secondary structures.
