As mentioned, the choice of 24 residue chain length used throughout this work is a fairly arbitrary choice. However, there are lower and upper bounds for forming stable helicesoligomers that are too short may not have enough native contacts to stabilize the helical backbone, and oligomers that are too long may entropically prefer to form more complex secondary or even tertiary structures involving hairpins. In this section, we repeated the heat capacity and native contacts analysis on replica exchange simulations of oligomers with varying chain length, ranging from 6 residues to 36 residues.
