[Spin label study of the structure and conformational properties of fibers from cotton grown from gamma-irradiated seeds].
According to ESR spectra of the radical - probe I it has been shown that there are two regions in cotton cellulose: ordered and disordered ones, pointing to inhibition and free rotation of the radical. 40 spin-labeled samples of cotton filaments and their mutants by the radicals II-IX chemically bound by the cellulose hydroxyl group were obtained. From ESR spectra strong inhibition of iminoxyl radical was established which was the evidenced of high rigidity of disordered regions of cellulose. Conformational changes of cotton cellulose grown from seeds exposed to different doses of gamma-irradiation.
