Dependence of the G value for radical production on the physical state.
Collagen was modified in several different ways which supplied a number of different samples. Their chemical composition (amino acid composition) was nearly equal; the physical properties (molecular weight and molecular organization) were different. The production of free radicals in these compounds was studied quantitatively with the electron spin resonance method. Differences in radical yield of at most a factor of 5 were observed. The results could be explained by assuming the presence of a radical-turnover process during irradiation, and the occurrence of a fast physical process of energy migration in ordered systems.
