What is radioactively labeled?

Radioactively labeled refers to a process by which a particular substance is marked or tagged with a radioactive element in order to track its movement or behavior. The radioactive labeling process can be applied to a wide range of compounds, including biological molecules such as proteins, carbohydrates, and nucleic acids, as well as drugs, chemicals, and other substances.

The most common way of radioactively labeling substances is by using a synthetic radioactive isotope of an element such as carbon, hydrogen, nitrogen, oxygen, or phosphorus. The isotope can be incorporated into the molecule through chemical synthesis or metabolic pathways.

Radioactive labeling is widely used in scientific research to study the behavior and interactions of molecules in various biological and chemical systems. For example, it can be used to track the uptake and distribution of drugs in the body, to measure the activity of enzymes and receptors, to study the metabolism of nutrients, and to investigate the dynamics of biochemical pathways.

However, the use of radioactively labeled substances also carries certain risks and requires strict safety measures to be taken in order to minimize exposure to radiation. This includes proper handling, storage, and disposal of radioactive materials, as well as monitoring of radiation levels and adherence to safety protocols.
