How does superoxide dismutase function in the body?

Superoxide dismutase (SOD) is an enzyme that plays a crucial role in maintaining the body's balance of harmful free radicals. It functions by catalyzing the conversion of superoxide radicals, highly reactive molecules that can damage cells and tissues, into hydrogen peroxide and molecular oxygen. This reaction is vital as it prevents the accumulation of superoxide radicals, which can cause oxidative stress and contribute to the development of various diseases such as cancer, diabetes, and neurodegenerative disorders. SOD exists in three forms: copper-zinc SOD, manganese SOD, and extracellular SOD, each localized in different cellular compartments to protect against specific sources of superoxide radicals. By scavenging and neutralizing these harmful radicals, SOD helps to maintain the integrity and proper functioning of cells and tissues.
