Used as a stable isotope tracer in metabolic research to study glucose metabolism pathways, including glycolysis, the Krebs cycle, and gluconeogenesis. Enables precise tracking of carbon flow in cells, tissues, or whole organisms using techniques like mass spectrometry or NMR. Commonly applied in cancer research, diabetes studies, and neuroscience to understand metabolic changes under disease conditions or drug treatments. Safe for use in human and animal studies due to non-radioactive labeling.
