Oleic Acid-13C (CAS 82005-44-5)

Oleic Acid-13C, assigned CAS number 82005-44-5, is a labeled analog of oleic acid, where the carbon-13 isotope (^13C) has been incorporated into the molecule. This specific modification makes it a valuable tool in various research fields, particularly in studies involving metabolic pathways and lipid biochemistry, where tracking and analysis of lipid utilization and degradation are necessary. Oleic Acid-13C retains the chemical properties of its unlabeled counterpart—a monounsaturated fatty acid primarily found in vegetable oils and animal fats, known for its cis-double bond at the ninth carbon, contributing to its liquid state at room temperature. The incorporation of the ^13C isotope does not alter the biological activity or physical properties of the molecule but enables researchers to use mass spectrometry and NMR spectroscopy to accurately trace the metabolic fate of oleic acid in complex biological systems. This isotopic labeling is crucial for studies focused on lipidomics, where understanding the dynamics of lipid metabolism and its implications on cellular processes is essential. Besides, Oleic Acid-13C has been used in environmental studies to trace organic carbon sources and transformations. This isotopic tool enhances the precision of biochemical studies by providing a non-invasive means to monitor and quantify biological processes, thereby contributing to a deeper understanding of lipid function in various biological and ecological contexts.
