Catalase is an enzyme that occurs in almost all aerobic organisms. Its main metabolic function is to prevent oxidative damage to tissues induced by hydrogen peroxide which is a strong oxidizing agent. Catalase is very ...

Reactive oxygen species damage intracellular targets and are implicated in cancer, genetic disease, mutagenesis, and aging. Catalases are among the key enzymatic defenses against one of the most physiologically abundant ...

The effects of the catalase-based gel in the release of residual oxygen in permanent human teeth submitted to 10% carbamide peroxide (Whitness perfect 10%) were assessed in vitro. The teeth were divided into specimens ...

The complexes formation between acid and basic polyelectrolytes (carrageenan and Eudragit ® EPO) with catalase was evaluated in order to understand the mechanism of their interaction. Catalase was selected as the model ...

Fatty acid (FA) may disturb the redox state of the cells not only by an increase in reactive oxygen species (ROS) generation but also due to a reduction in antioxidant enzyme activities. The effect of various FAs (palmitic, ...

Reactive oxygen species (ROS) are constantly produced by cells that promote cellular oxidative damage and are neutralized by an antioxidant system including superoxide dismutase, glutathione, peroxidase and catalase. Male ...
