(Stomach acid could potentially render it inactive by denaturing it, the way it does naturally during digestion of proteins.) Intravenous glutathione is an effective alternative, but it is costly and inconvenient

Using redox-specific cysteine-labeling strategies coupled with mass spectrometry, we quantified reversible oxidation states at individual cysteine residues (Figure 5A)
