The role of thiols in antioxidant systems
WebbHowever, HD therapy per se did not contribute to oxidative stress already present in uraemia. Owing to the variability in lipid peroxidation products as markers of oxidative stress and the vital role played by thiol antioxidants in the biological system, it is suggested that protein thiol oxidation may be a better marker of oxidative stress.
