DL-Cystine-d6（Cat No.:S000744） is a deuterated form of DL-cystine, where six hydrogen atoms are replaced with deuterium, enhancing its molecular stability. This makes it an excellent internal standard for analytical methods like mass spectrometry and NMR spectroscopy. DL-cystine consists of two cysteine amino acids linked by a disulfide bond, important in protein structure and function. The introduction of deuterium into DL-cystine-d6 allows for more accurate pharmacokinetic and metabolic studies, aiding researchers in understanding the compound’s stability, degradation, and role in forming disulfide bonds in proteins within biological systems.
