Glutathione (GSH), as an important exogenous substance, can improve the antioxidant defense ability of cells and plays an important role in regulating intracellular REDOX signal transduction [42]
Once delivered into cells, glutathione participates in recycling antioxidants, supporting detox enzyme pathways, and maintaining redox balance
It reduces oxidative damage, decreases viral replication, and strengthens defenses against environmental pollutants

Bacterial expression produces none of those and instead produces host-cell protein, host-cell DNA, endotoxin from the Gram- negative cell wall, species with incorrect or scrambled disulfide pairing, N-terminal heterogeneity from incomplete or over-enthusiastic processing of the initiator methionine and the leader region, methionine oxidation, deamidation, clipped forms generated by host proteases, and covalent or non-covalent aggregate
