For the quantification of sulfur metabolites in serum, the metabolites in 20 uL of serum were extracted and derivatized by NEM in 80 L of ice-cold extraction solvent (80% MeOH: 20% H2O containing 25 mM NEM and 10 mM ammonium formate, pH = 7.0) which includes stable isotope labeled internal standards (1 M [ 13 C 3 , 15 N]-cysteine-NEM, 0.1 M [ 13 C 2 , 15 N]-GSH-NEM, 2 M [D 4 ]-Cystine, 4.6 M [ 13 C 5 , 15 N 2 ]-GSSG, 5 M [D 4 ]-Hypotaurine, and 40 M [ 13 C 2 ]-Taurine followed by incubation at 4 C for 30 min

Its antioxidant properties can help neutralize inflammation-driven oxidative stress in the digestive tract
Based on the evidence that heat-shock proteins (Hsps) can exert neuroprotective effects against oxidative stress-related injury and that nutritional antioxidants are able to upregulate Hsps in neurons, use of nutritional antioxidants such as carnitine/acetyl-L-carnitine has been advocated to counteract the oxidative stress-induced brain damage in Alzheimer's disease [67, 119]
Protocol length: Short recovery-focused cycles may be different from longer maintenance-style protocols
Glutathione plays an important role in protecting the cells from oxidative stress and supporting immune function
