Glutathione

Glutathione Glutathione, commonly abbreviated GSH, is a naturally occurring tripeptide composed of glutamate, cysteine, and glycine. It is one of the body’s principal intracellular antioxidants and plays a central role in maintaining cellular redox balance. In laboratory research, glutathione is studied for its involvement in antioxidant defense, neutralization of reactive oxygen species, cellular detoxification, enzyme activity, protein regulation, and protection from oxidative stress. It also serves as an important cofactor for glutathione-dependent enzymes.
