Glutathione and mercury

Glutathione (USH)
Glutathione is an important antioxidant amino acid which protects against mercury toxicity. Glutathione is a tripeptide, made from the combination of three amino acids; L-glycine, L-glutaniic acid, and L-cysteine. Studies have shown that GSH levels are decreased during cases of mercury toxicity. It is interesting to note that GSH deficiency resulting from genetic errors mimic the acute mercury toxicity effects of Minamata disease. Without adequate OSH, mercury from the environment cannot be detoxified and eliminated.
