It has been shown that kinetics of the death of free radicals UV-induced at 77 degrees K in collagen is determined by two reactions having different rates. Such shape of the kinetic curve is substantiated by the spatial structure of macromolecules and permits to find easily the portion of peptide chains in the helical form and the portion of end peptides not incorporated in this structure. The degree of helical pattern of collagen from rat skin was shown to be 92%.
