Used in research to modulate glutathione synthesis pathways, particularly in studies related to oxidative stress, cellular defense mechanisms, and metabolic regulation. Helps investigate the role of glutathione depletion or enhancement in disease models such as neurodegenerative disorders, cancer, and liver diseases. Employed in cell-based assays to evaluate the impact of altered glutathione levels on cell viability, apoptosis, and response to toxins. Supports drug discovery efforts targeting redox balance and antioxidant capacity in cells.
