Mn 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 superoxide radicals, which are harmful byproducts of cellular metabolism, into less harmful molecules. This process helps maintain cellular health and function. The enzyme contains manganese, which is essential for its activity. Mn SOD is primarily located in the mitochondria, the energy-producing structures within cells. By neutralizing superoxide radicals, it helps prevent damage to cellular components, thereby supporting overall cellular integrity and longevity.
