Glutathione plays important roles in antioxidant defense, nutrient metabolism, and regulation of cellular events (including gene expression, DNA and protein synthesis, cell proliferation and apoptosis, signal transduction, cytokine production and immune response, and protein glutathionylation).

Glutathione (GSH, / ˌɡluːtəˈθaɪoʊn /) is an organic compound with the chemical formula HOCOCH (NH2)CH2CH2CONHCH (CH2SH)CONHCH2COOH. It is an antioxidant in plants, animals, fungi, and some bacteria and archaea.

This review is the introduction to a special issue concerning, glutathione (GSH), the most abundant low molecular weight thiol compound synthesized in cells. GSH plays critical roles in protecting cells from oxidative damage and the toxicity of ...

Glutathione (GSH) is present in all mammalian tissues as the most abundant non-protein thiol that defends against oxidative stress. GSH is also a key determinant of redox signaling, vital in detoxification of xenobiotics, regulates cell proliferation, …

Glutathione (GSH) is a tripeptide, which has many biological roles including protection against reactive oxygen and nitrogen species. The primary goal of this paper is to characterize the principal mechanisms of the protective role of GSH against reactive species and electrophiles.

Glutathione (GSH) has been the focus of increased scientific interest in the last decades. It plays a crucial role in all major physiological processes by supplying antioxidant defenses through participating in cellular redox reactions in the human body and other living organisms.

Jan 29, 2019 · Glutathione is a major antioxidant in all forms of life and an indicator of cellular oxidative stress. Reduction by the GSR enzyme utilizes NADPH as an electron donor. In a reduced form, glutathione is metabolized in multiple ways leading to the biosynthesis of mercapturonate, glutamate, glycine, cysteine and other amino acids.

Glutathione metabolism has till now been largely depicted and understood by the γ-glutamyl cycle that was proposed in 1970. However, new findings and knowledge particularly on the transport and degradation of glutathione have revealed that many aspects of …

May 30, 2019 · Glutathione plays important roles in nutrient metabolism, gene expression, etc. and sufficient protein nutrition is important for maintenance of GSH homeostasis. Glutathione is synthesized from glutamate, cysteine, and glycine sequentially by gamma-glutamylcysteine synthetase and GSH synthetase.

Mar 12, 2025 · Without adequate selenium, glutathione peroxidase activity declines, impairing oxidative defense. Zinc and magnesium further contribute by influencing the expression of glutathione-related enzymes. Sulfur-containing compounds such as alpha-lipoic acid (ALA) and methyl donors like folate and vitamin B12 support glutathione metabolism.
