Abstracts

EN

In structural studies on biological materials, among other methods, electrical techniques are used widely. Temperature dependence of electrical conductivity is a method permitting studies on denaturation, glass transition and water release - processes, which occur in solid-state proteins. Variations of amplitude and temperature of the peak on the recorded thermogram make it possible to draw conclusions about thermal stability and physicochemical processes occurring in the studied biological material. The shape of experimental curve is material-related and depends upon its "history". The paper is based on experimental results obtained mainly for collagen.
