S-(2-Carboxyethyl)-L-cysteine serves as a key biomarker for acrylamide exposure in toxicological and biochemical research. It is primarily used to study metabolic pathways, enzyme mechanisms, and detoxification processes in the body, particularly those involving the elimination of toxins and the formation of antioxidants. Additionally, it finds applications in pharmacological studies for developing drugs and dietary supplements aimed at treating and preventing conditions related to oxidative stress and inflammation.
