nac cysteine glutathione N-Acetylcysteine (NAC): Impacts on Human

Reduced glutathione (GSH) is a ubiquitous antioxidant, utilized as a source of reducing equivalents by different GSH peroxidases, which requires constant intracellular GSH synthesis from cysteine, glutamate, and glycine (1, 2)

When antigen presenting cells express IDO and begin degrading tryptophan, they take on a regulatory rather than activating phenotype (Lob et al., 2009

The millimolar GSH intracellular concentrations, the low plasma micromolar concentrations and the low GSH redox potential ( E 0 = 240 mV) make GSH an ideal and perfect cellular redox buffer (5, 1618)
