Used in cellular and metabolic research to study fatty acid transport and mitochondrial function, particularly in models of lipid metabolism disorders. It serves as a substrate to investigate the role of carnitine derivatives in the regulation of long-chain fatty acid oxidation. Applied in experimental assays to assess enzyme activity, such as carnitine palmitoyltransferase, and to evaluate metabolic flux in muscle and liver cells. Also utilized in studies exploring insulin resistance, obesity, and cardiovascular diseases where altered fatty acid metabolism is a factor. Its cis,cis configuration makes it a relevant analog for examining the behavior of unsaturated fatty acid conjugates in biological systems.
