Manganese SOD, or manganese superoxide dismutase, is an important enzyme found in many organisms. It plays a crucial role in protecting cells from oxidative stress by converting harmful superoxide radicals into less harmful molecules. This process helps maintain cellular health and function. This enzyme is particularly significant in the mitochondria, the energy-producing structures within cells. Manganese SOD is essential for various biological processes and is linked to the overall antioxidant defense system, which includes other enzymes like catalase and glutathione peroxidase. Its activity is vital for preventing cellular damage and supporting overall health.
