L-Cysteine-1-13C（Cat No.:S000680） is a labeled form of L-cysteine, where the alpha carbon atom is enriched with carbon-13. This isotopic labeling enhances its visibility in analytical methods such as NMR spectroscopy and mass spectrometry, making it particularly useful for studying metabolic pathways and protein interactions involving cysteine. L-cysteine is a crucial sulfur-containing amino acid, important for synthesizing proteins, supporting detoxification, and promoting antioxidant activities. The carbon-13 enrichment at the first position allows precise tracking and analysis of L-Cysteine’s incorporation into various biochemical processes and its behavior in biological systems.
