L-CYSTEINESULFINIC ACID Usage And Synthesis

Uses

L-Cysteinesulfinic acid is an NMDA and mGlu receptor agonist. In addition, used to probe conformational flexibility of human DJ-1 which is crucial in protecting against oxidative stress and other factors contributing to Parkinson’s.

Definition

ChEBI: The organosulfinic acid arising from oxidation of the sulfhydryl group of L-cysteine.
