The reaction catalyzed by -ECS/GSH1 is considered the rate-controlling step of GSH synthesis, and the activity of this enzyme is regulated by cellular levels of cysteine and glutamic acid, and feedback inhibition by -EC and GSH ( Figure 1 GSH1 (EC 6.3.2.2) is exclusively present in plastids, while GSH2 (EC 6.3.2.2) has dual localization in plastids and the cytosol, both encoded by a single gene ( 2 O 2 and organic hydroperoxides, as well as their involvement in regulating cellular redox homeostasis by maintaining thiol/disulfide or NADPH/NADP+ ratios ( Deficiency in the activity of either GSH1 or GSH2 impairs GSH production, negatively impacting plant growth and development

In line with this observation, the pre-administration of DSePA (2 mg/Kg bodyweight) for five consecutive days significantly improved the 30-day survival of mice against the lethal dose (-rays, 10 Gy) of WBI by preventing lipid peroxidation, DNA damage, and apoptosis in the radiosensitive organs like the spleen and small intestine [88, 89]
Nutrition interventions are growing in popularity
Example: 10mg vial + 1mL water = 10mg/mL = 10,000mcg/mL Write this concentration on the vial with a permanent marker along with the reconstitution date
