[Mechanical destruction of collagen].
Mechanical destruction of collagen was studied by means of electrophoresis in polyacrylamid gel and ESR-spectroscopy. It has been stated that the rates of the breakage of polypeptide chains measured by these two methods are in a good agreement. An analysis of ESR spectra of free radicals in collagen suggests that mechanical action induces the rupture of C alpha-N-bonds.
