Depolarization thermal current study of keratin for high water contents


The characteristics (temperature and activation energy) of peak I for S.C., hair and ice are very close. This fact implies, at high water content in the keratin structures, the existence of water molecules loosely bound to the protein. In hair, the sorption isotherm increases more rapidly in this range and molar heat of sorption, which is 13.6 Kcal/mole at… (More)
