glutathione system in plants Peroxidases Plants: Innumerable Role in Abiotic Stress Tolerance and Plant Development | Journal of Plant Growth Regulation Glutathione-dependent redox homeostasis is critical

Every cell in your body produces free radicals unstable molecules created during normal metabolism, and in much larger numbers when you're dealing with pollution, poor sleep, alcohol, or a stressful deadline

Glutathione biosynthesis occurs in several, but not in all eukaryotic cell types through a well-coordinated and feedback-modulated process that needs one essential amino acid, cysteine, and two others, glutamic acid and glycine, that most cells can synthesize themselves from the intermediates of core metabolism

During aging, OS represents a primary process that directly impairs the central nervous system [54]
