[20-13C]-Arachidonic acid

[20-13C]-Arachidonic acid is a stable isotope-labeled form of arachidonic acid, an unsaturated fatty acid that is commonly found in the phospholipids of cell membranes. Arachidonic acid is an important precursor to a variety of signaling molecules, including prostaglandins, thromboxanes, and leukotrienes, which play important roles in inflammation, blood clotting, and other physiological processes. The incorporation of the carbon-13 isotope at the 20th carbon position of arachidonic acid allows for the tracking of the molecule in complex biological systems using mass spectrometry techniques. This labeling technique has been used to study the metabolism, distribution, and regulation of arachidonic acid in various tissues and cell types. [20-13C]-Arachidonic acid has been used in numerous studies to investigate the role of arachidonic acid and its metabolites in a variety of physiological and pathological conditions, including inflammation, cardiovascular disease, and cancer. This labeled form of arachidonic acid is particularly useful for studying the kinetics of arachidonic acid metabolism and the production of specific prostaglandins and other downstream metabolites. Overall, [20-13C]-Arachidonic acid is a valuable tool for researchers studying the complex biochemistry of arachidonic acid and its role in various physiological and pathological processes.
