L-Aspartic Acid-d3 (CAS 3842-25-9)

L-Aspartic Acid-d3 is a labeled variant of L-aspartic acid, where the "d3" indicates the incorporation of three deuterium atoms. The incorporation of deuterium atoms allows L-Aspartic Acid-d3 to be used as an internal standard in mass spectrometry and NMR (nuclear magnetic resonance) spectroscopy studies. These techniques are critical for quantifying concentrations of molecules in complex mixtures, understanding molecular structures, and studying the dynamics of biochemical processes. The deuterium labeling provides a distinguishable mass difference that can be used to trace the distribution and metabolic pathways of L-aspartic acid in biological systems without interfering with the system′s natural function. L-Aspartic acid itself is a non-essential amino acid playing pivotal roles in the biosynthesis of other amino acids and in the urea cycle, a critical pathway for the elimination of ammonia from the body. The labeled version, L-Aspartic Acid-d3, thus enables researchers to delve into the metabolic fate of aspartic acid in organisms, and understand its participation in metabolic cycles.
