[The effect of water and secondary structure on the thermal stability of macroradicals in proteins]

The thermostability of macroradicals located in the protein peptide chain segments with the different secondary structure was investigated. It has been shown at the dry proteins that just the secondary structure determines the thermostability of the macroradicals. In the different proteins the thermostability of macroradicals in peptide chain segments with identical secondary structure is the same. The thermostability of free radicals is the same in aqueous solutions of the different proteins.
