[Jump-like change in the heat capacity of denatured biological macromolecules].
Study of temperature dependence of heat capacity in denatured biopolymers (collagen, elastin, lysozyme, DNA) with 10-15% of bound water revealed a characteristic jump at some critical temperature Tc. It is argued that such behavior reflects glass transition in biopolymers.
