isotopic labeling

Isotopic labeling is a scientific technique where atoms in a molecule are replaced with isotopes—versions of elements that have a different number of neutrons. This allows researchers to trace the path of these labeled molecules in various processes, such as metabolism or chemical reactions. By tracking these isotopes, scientists can gain insights into how substances move and interact within complex systems, providing valuable information in fields like biology, chemistry, and environmental science. Essentially, it helps illuminate otherwise invisible processes by highlighting specific components of a mixture.
