Decreased carbon centered and hydrogen radicals in skeletal muscle of vitamin E supplemented rats.
Carbon centered and hydrogen radicals were examined using electron spin resonance techniques with 5,5 dimethyl-2-pyrroline-1-oxide in the skeletal muscle of rats fed with a control diet and a vitamin E supplemented diet containing alpha tocopherol. Carbon centered and hydrogen radical levels in the white and red muscles and the soleus of these vitamin E treated muscle fibers were decreased. These results suggest that vitamin E directly quenches these free radicals.
