Pentadecanoic Acid

Pentadecanoic Acid (CAS No.: 1002-84-2) is a long-chain saturated fatty acid with a 15-carbon backbone that is widely utilized in biochemical and metabolic research as a representative odd-chain fatty acid. It is found in trace amounts in certain dietary sources and biological systems, where it serves as a biomarker of lipid metabolism and nutritional status. Functionally, pentadecanoic acid has been associated with modulation of enzymatic activity within specific signaling pathways, contributing to the regulation of cellular processes such as inflammation, lipid homeostasis, and energy metabolism. Although its precise molecular targets are not fully characterized, studies suggest that it can influence key metabolic and inflammatory signaling cascades, making it a useful tool for investigating mechanisms underlying metabolic disorders and immune responses. In vitro studies typically employ concentrations in the low micromolar to millimolar range depending on the cellular context, while in vivo applications vary according to experimental design and model system. Pentadecanoic acid is therefore commonly applied in cell-based assays and animal models to explore lipid-mediated signaling, metabolic regulation, and the development of therapeutic strategies targeting metabolic and inflammatory diseases.
