Oleic Acid-13C is widely used in research and diagnostic fields, particularly in metabolic studies and lipid metabolism research. Its labeled carbon atom allows for precise tracking and analysis of fatty acid pathways in biological systems, making it valuable for understanding lipid-related diseases such as obesity, diabetes, and cardiovascular disorders. Additionally, it serves as a critical tool in isotope labeling experiments to study the synthesis, degradation, and distribution of lipids in cells and tissues. Its application extends to the development of advanced imaging techniques like mass spectrometry and NMR spectroscopy, where it aids in improving the accuracy of lipid profiling and biomarker discovery.
