Glutathione

Glutathione is a naturally occurring tripeptide composed of three amino acids—glutamine, cysteine, and glycine—extensively studied in scientific research for its role in cellular antioxidant defense, detoxification, and redox balance in various model systems. In laboratory settings, glutathione is often used to investigate mechanisms related to oxidative stress regulation, free radical neutralization, and maintenance of intracellular homeostasis. Its structure and biochemical properties continue to be of interest in in vitro studies focused on cellular metabolism, signaling pathways, and protective responses against oxidative damage.
