Glutathione, 600mg

Glutathione (GSH) is a tripeptide thiol composed of glutamate, cysteine, and glycine, and is among the most extensively studied low-molecular-weight redox-active molecules in biological systems. Through its reactive sulfhydryl group, GSH participates in oxidation-reduction reactions, thiol-disulfide exchange processes, and cofactor-dependent enzymatic mechanisms. It serves as an obligate co-substrate for multiple enzyme families, including glutathione peroxidases (GPx), glutathione S-transferases (GST), and glutaredoxins, where it contributes to redox-regulated biochemical pathways and enzyme-mediated signaling processes.

Experimental investigations have extensively utilized GSH for studies of redox biology, thiol chemistry, enzyme-cofactor interactions, glutathione-dependent regulatory networks, and signal transduction mechanisms involving sulfur-containing biomolecules. Research applications include glutathione system characterization, GPx and GST pathway investigation, glutaredoxin-associated signaling studies, redox system analysis, and mechanistic evaluation of thiol-dependent biochemical processes.
