Aspects of radiation chemistry of polysaccharides (review)
Description
The data on the radiolysis of polysaccharides (in the form of aqueous solutions in liquid or frozen states, and native dry preparations) including the possibility of participation of free radicals in formation of ruptures in macromolecules, low-molecular products of polysaccharides decomposition, carbonyl, carboxyl and peroxide groups in the macromolecules are generalized and discussed. The reaction schemes for principal transformation pathways of polysaccharides free radicals are given. The effects of the adsorbed structured water on formation and conversions of free radicals, of postradiation polymer decomposition, and radiation protection of polysaccharides are discussed
Abstract (Russian)
Обобщены и обсуждаются данные исследований по радиационной деструкции полисахаридов (в водных и замороженных растворах: нативных, сухих препаратов) - механизмы образования разрывов в макромолекулах, карбонильных, карбоксильных и пероксидных групп в составе полимера, низкомолекулярных продуктов радиолиза, пострадиационные процессы деструкции с участием свободных радикалов. Приведены схемы основных направлений превращения макрорадикалов. Обсуждаются роль радиолиза структурированной полимером воды в деструкции полисахаридов, проблемы радиозащиты и стимулирования деструкции полисахаридсодержащих системAdditional details
