Folic acid-15N,13C5 is the 13C5 and 15N labeled Folic acid .
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].
Folic acid plays a critical role in the prevention of chromosome breakage and hypomethylation of DNA[2].
