normal range human serum glutathione A simple assay for in whole blood Is Glutathione the Master Antioxidant?

The antioxidant activity of GSH intermediated via thiol (-SH) of its cysteine residue upon its interaction with ROS or electrophiles and the GSH oxidized to GSSG (oxidized Glutathione), the GSSG will reduce to GSH by Glutathione reductase (GR), the activity of GR is therefore very important to keep the antioxidant power of mammalian cells, while GSH/GSSG ratio is an indicator for redox balance in the cell

The analytical technique in that study (liquid chromatographyisotopic dilution mass spectrometry) more closely resembles the LCMS/MS assay we used than does the HPLC technique used by Borgstrm and colleagues in their 1986 study [4]

Before evaluation, participants washed their faces using face cleanser, soap, and water
