They may involve thiol-disulfide exchange between protein thiol groups and GSSG, perhaps catalyzed by certain GRX, occur through conversion of cysteine thiol groups to thiyl radicals or sulfenic acids, or be mediated by GSNO (Dixon et al., 2005
protection against free radicals and toxins
the polypeptide, C1 0 H17N 3 O6S, of glycine, cystine, and glutamic acid makes glutathione which occurs widely in plant and animal tissues and is important in biological oxidation-reduction reactions
Formulations composed of food-grade surfactants and lipid excipients engineered as micellar, liposomal, emulsion-based, and lipid nanoparticle systems are emerging in the supplement market
In terms of pharmacological properties, DON and BPTES show moderate potency, poor metabolic stability, low water solubility, and limited selectivity for GLS, resulting in inferior antitumor efficacy compared to CB-839 (246, 247)
