Subsequent reperfusion triggers an abrupt overproduction of ROS, including hydrogen peroxide, superoxide anion, hydroxyl radical, singlet oxygen, hypochlorous acid, and nitric oxide 33 , amplifying oxidative stress and aggravating tissue injury
Nutrient Deficiencies (Building Blocks Missing) Glutathione synthesis requires specific nutrients: Cysteine : From dietary protein (whey, eggs, poultry)-rate-limiting Glycine : Often deficient in modern diets (need 10-15g/day, most get 3-5g) Selenium : Cofactor for glutathione peroxidase (GPx) , the enzyme that recycles GSSG back to GSH B vitamins (B6, B9, B12): Required for methylation and sulfur metabolism Vitamin C : Recycles oxidized glutathione Deficiency in any of these impairs glutathione production or recycling [5]
Heavy Metal Chelation : Glutathione's sulfur-containing cysteine residue has a strong affinity for heavy metals like mercury and lead
As GSH is used to support all of the latter processes, it is regenerated by reactions including the reaction catalyzed by glutathione reductase (GR), which requires NADPH as a coenzyme

Resuspended resin just means that you want to invert the bottle of agarose resin a few times to make sure that all the beads are off the bottom of the bottle and in solution before you pipet some out of there
