DL-Histidine-d3（Cat No.:S000715） is a deuterated form of DL-histidine, where three hydrogen atoms have been replaced with deuterium, enhancing its molecular stability. This modification makes it valuable as an internal standard for precise analytical methods such as mass spectrometry and NMR spectroscopy. DL-histidine is a racemic mixture of the L- and D-isomers of the amino acid histidine, important for protein synthesis and as a precursor to several neurotransmitters and biologically active peptides. The incorporation of deuterium in DL-Histidine-d3 allows for more accurate pharmacokinetic and metabolic studies, providing clearer insights into its behavior in biological systems.
