Superoxide Dismutase (SOD) is an important enzyme found in nearly all living organisms. It plays a crucial role in protecting cells from damage caused by reactive oxygen species, particularly superoxide radicals. By catalyzing the conversion of superoxide into oxygen and hydrogen peroxide, SOD helps maintain cellular health and prevents oxidative stress. There are several types of SOD, including Cu/Zn SOD, Mn SOD, and Fe SOD, each distinguished by their metal co-factors. These enzymes are present in various cellular compartments, such as the cytoplasm and mitochondria, and are vital for processes like aging and inflammation regulation.
