Cat. No.: HY-113110
CAS No.: 19246-18-5
Purity:  99.96%
Synonyms: L-Cysteinylglycine; Cys-Gly; H-Cys-Gly-OH
Cysteinylglycine (L-Cysteinylglycine; Cys-Gly) is a dipeptide formed by the peptide bond linkage between cysteine (Cysteine) and glycine (Glycine). Cysteinylglycine is an important metabolic intermediate in the human body, mainly derived from the degradation of glutathione (GSH). Cysteinylglycine reduces ferric iron to ferrous iron, drives the redox cycle of iron, generates reactive oxygen species (ROS), stimulates oxidative reactions, induces lipid peroxidation of human plasma LDL lipoproteins, and causes oxidative damage to DNA bases. Cysteinylglycine can be used as a biomarker to evaluate ischemic heart disease, breast cancer and other conditions .

Propanedial (Malondialdehyde) (13.88 mM in water) is one of the final products of lipid peroxidation. Propanedial causes protein inactivation, DNA damage and cross-linking by forming stable covalent adducts with biological macromolecules, which is the main mechanism for its cytotoxicity and genotoxicity. Propanedial production increases with the elevation of free radicals. Propanedial is a key biomarker for evaluating the level of cellular oxidative stress [1][2][3].
