Understanding the Glutathione Duo: GSH and GSSG

Glutathione (GSH) is a tripeptide thiol antioxidant found abundantly in cells, acting as a primary defense against reactive oxygen species (ROS) and reactive nitrogen species (RNS). It directly scavenges free radicals and serves as a substrate for various enzymes, such as glutathione peroxidase and glutathione S-transferase, which are crucial for detoxification.

When glutathione (GSH) acts as an antioxidant, it is oxidized to form GSSG. This conversion is catalyzed by glutathione peroxidase. The ratio of GSH to GSSG (the GSH/GSSG ratio) is a sensitive indicator of the intracellular redox state.Total Glutathione (T-GSH)/Oxidized Glutathione (GSSG) ... A decrease in this ratio signifies oxidative stress, where the production of ROS overwhelms the cell’s antioxidant capacity. Therefore, accurately measuring both GSH and GSSG is paramount to understanding cellular health.
