DL-Homocystine-3,3,3’,3’,4,4,4’,4’-d8（Cat No.:S000610） is a deuterium-labeled version of homocysteine, where eight specific hydrogen atoms at positions 3 and 4 on both cysteine units of the dimer are replaced with deuterium (D). This heavy labeling enhances the molecule’s traceability and stability in analytical studies using techniques such as mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. It allows researchers to investigate the metabolic pathways of homocysteine, particularly its role in methylation and its link to cardiovascular and neurodegenerative diseases.
