glutathione peroxidase activity in liver liver, kidney, and spleen. Values The Selenoprotein Glutathione Peroxidase 4:

Intra- and extra-cellular metabolite concentrations were normalised by total protein concentration of the cell lysate and expressed as nmol metabolite/mg protein

Notably, GST and GPx activities were higher under aerobic conditions (0.32 and 20.64 nmol mg 1 protein, respectively) compared to anaerobic conditions (0.26 and 17.27 nmol mg 1 protein)

Glutathione suppresses the enzyme tyrosinase, which plays a key role in melanin synthesis, thereby lightening the skin over time

The seeding density was set at 1 10 4 cells per well, and the plate was incubated for a period of 24 h in RPMI culture medium containing 10% FBS and 1%penicillinstreptomycin in a 37 C incubator with 5% CO 2 and appropriate humidity to allow for cell attachment and growth
