Antioxidant Evaluation

Hydroxyl radical (•OH) is one of the most reactive oxygen species with the strongest oxidative activity. The key to hydroxyl radical scavenging capacity assays lies in clearly defining how a sample interferes with the •OH generation process, the competitive reaction process, or the oxidative ...

Superoxide dismutase (SOD) is one of the most important antioxidant defense enzymes in biological systems. It catalyzes the dismutation of superoxide anion radicals (O2•−) to generate hydrogen peroxide and molecular oxygen, thereby suppressing the amplification of reactive oxygen species and ...
