Electronic specific heat of an α3-helical polypeptide and its biochemical variants

► Energy spectra of the α3-helical polypeptide and its 5Qα3 and 7Qα3 variant structures. ► Electronic specific heat (ESH) at constant volume of the polypeptides in focus. ► Possibility of using the ESH profiles as a tool for early diagnosis of amyloidosis-like diseases. ► Interesting for physical chemistry and biological researchers.
