L-Glutamine-15N is the 15N-labeled L-Glutamine, a non-essential amino acid abundantly present throughout the body and involved in many metabolic processes. It provides a source of carbons for oxidation in some cells. Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process.
- Can be 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 affect the pharmacokinetic and metabolic profiles of drugs
- Purity: 99.6%
