Protective efficiency, Salmonella

The results on the cellular protection against N()2 can be interpreted as the N()2 reacting with the three antioxidants to produce their radicals, with ascorbic acid reacting least efficiently, probably due to the lower reduction potential of its radical. Moreover, Arroyo et al. (1992) reported that NO - and N02 -induced mutations in Salmonella typhimurium TA1535 were inhibited efficiently by P-CAR and tocopherols, but not at all by ascorbic acid.
