ABSTRACT

Proteins represent high-molecular organic compounds with molecular weight varying from dozens to hundreds of thousand units. They are the main components of cells and are accumulated in seeds and eggs in the form of nutrients. Protein molecules in the cell perform various functions (immunity, respiration, muscular contractions, enzymatic catalysis, etc.) [I]. As radiation affects the cell, the energy received is finally absorbed by protein molecules (total concentration of dry protein in the cell reaches 60 wt.%, on average). Therefore, the knowledge of initial damage localization in protein molecules and the mechanism of propagation by them is important for forecasting the cell radiation consequences and cell radioprotection, i.e. for the purposes of applied radiobiology. We also face the problem of the radiation action estimation in case of food preservation [2]. Hence, of importance is to know the origin and the quantity of protein radiolysis products formed, some of which may be toxic.
