Methionine-d3（Cat No.:I043918）is a stable isotope-labeled version of the amino acid methionine, where the sulfur atom is replaced with a deuterium atom (denoted as “d3”). This isotope labeling is useful in scientific research, particularly in metabolic studies, as it allows for precise tracking of methionine’s incorporation into proteins and other metabolic pathways. Methionine-d3 is commonly used in proteomics, metabolic flux analysis, and studies involving protein synthesis, helping researchers better understand cellular processes and diseases. Its use in isotopic labeling offers an effective tool for exploring the dynamics of amino acid metabolism.
