An amino acid derivative with neuropathological interest. An NMDA receptor ligand

ChEBI: An S-substituted L-cysteine where the S-substituent is specified as a sulfo group.

L-Cysteine S-sulfate (LCSS) is used as an NMDA glutamatergic receptor agonist. It serves as a substrate for cystine lyase(s).
Cysteine is one of the functional amino acids th at are associated with growthreproductionmaintenance and immunity. Cysteine is a source of disulfide linkage in protein and is associated with sulfur transport. at physiological pHcysteine undergoes rapid oxidation to form cystine. Reduced availability of cysteine or cystineinfluences leukocyte metabolism. L-Cysteine serves as a precursor for the rate limiting step in glutathione synthesis th at occurs in neurons. It donates inorganic sulfate for detoxification reactions. ThereforeL-cysteine might be associated with neuroprotection. It is found to obstruct the entry of heavy metal ions across the blood-brain barrier into the brain. Increased levels of L-cysteine might lead to neurotoxicit
