Medchemexpress LLC DL-Alanine-d3 (DL-2-Aminopropionic acid-d3) | 53795-94-1 | MFCD00084106 | 50 MG
DL-Alanine-d3 is the deuterium labeled DL-Alanine, an amino acid that is the racemic compound of L- and D-alanine. It functions as a reducing and capping agent with silver nitrate aqueous solutions for nanoparticle production. It is also used in research for transition metal chelation, such as Cu(II), Zn(II), and Cd(II). This amino acid, classified with glycine and sodium saccharin as a sweetener, plays a key role in the glucose-alanine cycle between tissues and the liver.
- Used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
- Stable heavy isotopes can be incorporated into drug molecules for quantitation during drug development
- Deuteration may affect pharmacokinetic and metabolic profiles of drugs
