Displaying 10 results of Penicillin Stable Isotopes Penicillin Stable Isotopes are a type of penicillin molecule that contains stable isotopes of carbon, nitrogen, and oxygen. These isotopes do not decay over time and can be used in research to track the fate of penicillin in the body. This can provide insights into how the drug is metabolized and eliminated, which can inform the development of more effective antibiotics. Additionally, Penicillin Stable Isotopes can be used in forensic science to trace the source of penicillin contamination in food or other materials.
