L-Cysteine-15N（Cat No.:S000681） is a labeled form of L-cysteine where the nitrogen atom is enriched with nitrogen-15, enhancing its detectability in analytical methods such as NMR spectroscopy and mass spectrometry. This labeling is particularly useful for studying nitrogen metabolism and protein synthesis involving cysteine, a sulfur-containing amino acid essential for making proteins, supporting detoxification, and acting as an antioxidant. The 15N enrichment allows for detailed tracking and analysis of L-cysteine’s role and transformations in biological systems, providing crucial insights into its involvement in biochemical processes and its behavior in physiological contexts.
