The primary function of glutathione reductase (GR) is to catalyze the reduction of oxidized glutathione (GSSG) back to its reduced form, GSH. This process is essential because GSH is utilized by various enzymes, including glutathione peroxidase, for the detoxification of harmful reactive oxygen species (ROS) and organic hydroperoxides. Without sufficient GR activity, cells can accumulate GSSG, leading to a depletion of the essential reduced glutathione pool and an increased vulnerability to oxidative stress. Research has shown that GR is an essential enzyme that helps in maintaining the supply of reduced glutathione-GSH, highlighting its significance in cellular health.
