L-Glutathione with CAS 70-18-8
What is L-Glutathione？
L-Glutathione (GSH) is a naturally occurring tripeptide composed of three amino acids: glutamic acid, cysteine, and glycine. It is the most abundant intracellular antioxidant in the human body and plays a fundamental role in cellular defense, detoxification, and metabolic regulation.
In its reduced form (L-Glutathione Reduced), GSH acts as the active antioxidant species. It scavenges free radicals, regenerates other antioxidants such as vitamins C and E, and participates in the synthesis and repair of DNA. Its thiol (-SH) group is the key functional site responsible for its wide range of biochemical activities.
