Description

Application

• Superoxide dismutase activity as a measure of hepatic oxidative stress in cattle following ethionine administration.: This study evaluates the hepatic oxidative stress in cattle induced by ethionine administration by measuring superoxide dismutase activity. The findings suggest a significant oxidative response, highlighting the role of DL-Ethionine in studying liver oxidative mechanisms (Abd Ellah et al., 2009).

Biochem/physiol Actions

DL-Ethionine is a racemic mixture of the anti-methylation agent L-Ethionine and its enantiomer D-Ethionine. DL-Ethionine is used as a dietary supplement to accelerate cholangiocarcinogenesis in vivo. DL-Ethionine is used to induce oxidative stress in liver to study the levels and activities of anti-oxidative enzymes and compounds such as glutathione.
