Lysosomal cyst(e)ine can be mobilized to maintain glutathione synthesis and glutathione peroxidase 4 activity, thereby limiting lipid peroxidation. glutathione peroxidase gsh px inhibited by iron ncbi Several lines of antioxidant defense against oxidative stress: antioxidant enzymes, nanomaterials with multiple enzyme mimicking activities, and low molecular weight antioxidants The glutathione
