L-Histidine-d5 hydrochloride hydrate（Cat No.:S000603） is a deuterium-labeled variant of the amino acid histidine, where five hydrogen atoms are replaced with deuterium (D), and it is presented as a hydrochloride salt in a hydrated form to improve stability and solubility. This labeling enhances the molecule’s detection and quantification in scientific studies using techniques like mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. L-Histidine-d5 is particularly useful for studying histidine’s metabolic pathways and role in enzyme activity, histamine production, and buffering properties in physiological processes.
