L-Cysteinesulfinic acid monohydrate（Cat No.:R000067）is a sulfur-containing amino acid derivative formed during cysteine metabolism. It acts as a key intermediate in the biosynthesis of hypotaurine and taurine, which are important for osmoregulation, bile salt formation, and antioxidative defense. L-Cysteinesulfinic acid also participates in transamination and decarboxylation reactions, linking sulfur metabolism to neurotransmitter pathways. Researchers use it to study amino acid metabolism, redox biology, and neurological processes involving taurine. Its role in sulfur biochemistry makes it valuable for metabolic, neurological, and endocrinology-related research applications.
