Description

L-Threonine-¹³C₄ is the ¹³C labeled L-Threonine[1]. L-Threonine is a natural amino acid, can be produced by microbial fermentation, and is used in food, medicine, or feed[2].

In Vitro

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. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
