What is cellular glutathione?
Introduction. The tri-peptide gamma-glutamyl-cysteinyl-glycine (glutathione) is the major cellular antioxidant to combat reactive oxygen species (ROS). GSH is an antioxidant and a substrate for anti-oxidant enzymes such as selenium-dependent GSH peroxidase that neutralizes H2O2 and other free radicals.
What are cellular glutathione levels?
Reduction. GSH is found in the cytosol of cells where it is in the range of 1–10 mM (Meister 1988). In most cells the GSH concentration is about 1–2 mM, while in hepatocytes, which export GSH, the concentration can reach about 10 mM.
What is the role of glutathione in the body?
Glutathione acts as an important antioxidant in your body. That means it helps combat free radicals. Glutathione plays a role in many chemical reactions in your body. It also helps detoxify chemicals, including some that your body creates naturally, as well as pollutants and drugs.
What is intracellular glutathione?
Glutathione is a tripeptide that contains L-cysteine, L-glutamic acid and glycine. It is the smallest intracellular protein thiol molecule in the cells, which prevents cell damage caused by reactive oxygen species such as free radicals and peroxides.
Is glutathione safe to take everyday?
Glutathione is a very strong antioxidant that the body makes and uses every day. Researchers have associated low levels with several medical conditions. While supplements may be appropriate for some people, they may not be safe for everyone, and they could interact with other medications a person is taking.
