Displaying 8 results of Taurine Stable Isotopes Taurine stable isotopes are isotopes of taurine, a naturally occurring amino acid found in many biological tissues. These isotopes have a stable atomic nucleus, allowing them to be used in research to investigate metabolic pathways and physiological processes involving taurine. Taurine stable isotopes can also be used as tracers to study the uptake, distribution, and metabolism of taurine in living organisms.
