Displaying 10 results of Epinephrine Stable Isotopes Epinephrine Stable Isotopes are a set of isotopes used to study the metabolic pathways and physiological effects of epinephrine. These isotopes have the same chemical properties as natural epinephrine but differ in the number of neutrons in their nuclei. They are used in research to track the distribution and metabolism of epinephrine in the body, as well as to understand its role in various physiological processes. These isotopes are stable and do not decay, making them safe to use in experiments.
