DL-GLUTAMIC ACID (2,3,3,4,4-D5) is a deuterium-labeled, free amino acid belonging to the acidic amino acid class, featuring a side chain with a terminal carboxylic acid and a backbone bearing both amino and carboxyl functional groups. The molecule is specified as the DL stereochemical mixture and incorporates five deuterium atoms at the positions 2, 3, 3, 4, and 4, while retaining the glutamate connectivity and the carboxyl-bearing side chain that can participate in ionic interactions and hydrogen bonding. As an isotopically labeled glutamic acid, it is used in isotopic tracing, mass spectrometry-based analytical method development, and quantitative studies that require discrimination of glutamate-derived fragments or monitoring of glutamate handling in chemical or biochemical experimental workflows.
