glutathione glycine synthesis from and glutamine; 'retro-control' by Mode of action of Glutathione

Dietary antioxidants such as vitamins C and E are generally required in very small amounts, working with endogenous antioxidants to maintain or re-establish redox homeostasis [53]

Fumaric acid (FA) is an organic acid (C 4 H 4 O 4 ) omnipresent in nature and attributed with such properties (e.g., antioxidant, anti-inflammatory, analgesic, chemopreventive, anti-psoriatic, immunomodulatory, and neuroprotective) that may bestow relief in Cd-induced liver damage

This balance influences numerous redox-regulated cellular processes, including the modulation of signaling pathways, post-translational modifications such as protein glutathionylation, activation of transcription factors like Nrf2 and NF-B, and the regulation of cell fate decisions such as proliferation or apoptosis [38]
