Glutathione

Glutathione is a tripeptide composed of cysteine, glutamine, and glycine, and is one of the principal endogenous antioxidant molecules studied at the cellular level. It is used in laboratory research on redox biology, detoxification pathways, and oxidative stress.
Studied for (preclinical / in vitro research):
• Cofactor role in Phase II hepatic detoxification (glutathione-S-transferase pathway)
• Reactive oxygen species (ROS) scavenging activity in oxidative stress models
• Melanin synthesis and tyrosinase pathway modulation in vitro
• Cellular redox signaling (GSH/GSSG ratio) research
• Immune cell function and lymphocyte proliferation in preclinical models
• Mitochondrial oxidative stress research
