L-Methionine-1-13C (Cat No.: C000255) is a stable isotope-labeled form of L-Methionine, an essential amino acid. This labeled compound is used in medical diagnostics, particularly in L-Methionine-1-13C breath tests that assess hepatic regeneration. In these tests, the labeled methionine is administered, and the body’s metabolic processes break down the labeled methionine, leading to the release of labeled carbon dioxide. By measuring the labeled carbon dioxide in exhaled breath, healthcare professionals can gather information about liver function and regeneration.
