Conformation-Determined Segmental Dynamics in α‑Poly‑l‑Lysine Hydrobromide: The Impact of Thermally Induced β‑Sheet Formation on the Glass Transition Temperature
Solid-state polypeptides undergo continuous conformational reorganization when subjected to various environmental stimuli, reshaping their macroscopic physical behavior. Here, we investigate this phenomenon specifically under thermal treatment using α-poly-l-lysine hydrobromide (α-PLL), an ionic polypeptide containing...
