Precursor metabolites of GSH metabolism. Glycine, cysteine, glutamate, and glutamine represent GSH precursors, while 5-oxoproline is a marker of GSH degradation within the cell. Data are presented as a percentage of the control group. + p < 0.05, ++ p < 0.01 vs. control; * p < 0.05, ** p < 0.01 and *** p < 0.001 vs. RSL3. n = 4–6 per group.
