Probability distribution of the helix starting (N-terminal side) position (Left) and length (Right) at pH 1 (Top), 5 (Middle), and 8 (Bottom) for the C peptide simulated at 0.1 M ionic strength (dotted bars) and in pure water (solid bars) as well as for RN24′ at pH 5 (Middle, dashed bars). The values at 0 correspond to the unfolded states.
