Abstract:
Hydrogen peroxide (H2O2) and the superoxide radical (O2_) are normally present at low concentration as metabolites in aerobic cells. The generation of H2O2 in turkey muscle tissues was determined by using [14C]formate oxidation to 14CO2by the peroxidative activity of catalase. The incubation of muscle tissues at 37 °C shows H2O2 generation of 14.0 nmol/g of fresh weight/30 min. In the presence of added catalase we found that muscle tissues generate almost 26.6 nmol of H2O2 under the same conditions. Muscle tissues aging at 4 °C increase the generation of H2O2. It seems that endogenous generation of H2O2 plays an important role in the formation of the primary pool of biological catalysts in muscle tissues. © 1985, American Chemical Society.
