[en] The change in functional composition and molecular mass of crab, shrimp, and Antarctic shrimp (krill) chitin under the effect of ionizing radiation has been studied. By electron paramagnetic resonance spectroscopy it was established that primary radicals appear in positions 1 and 4 of the pyranose ring with subsequent breakdown of the glycoside bond analogous to cellulose and chitosan decay when γ-irradiated. A scheme of radiochemical transformations of chitin is suggested

AbstractAbstract

[en] Change of chitin functional composition and molecular mass in crabs, shrimps and other crustaceans under effect of ionizing radiation is studied. It is established through ESR spectroscopy method that primary radicals originate in the positions 1 and 4 of pyranose cycle with subsequent decomposition of glycoside coupling similarly to cellulose and chitosan decomposition by γ-radiation. Mechanism of chemical transformations is proposed
