All-cis-7,10,13,16,19-Docosapentaenoic acid

All-cis-7,10,13,16,19-Docosapentaenoic acid, commonly abbreviated as DPA or DPAn-6 and also known by the shorthand notation 22:5n-6 or clupanodonate, is a 22-carbon omega-6 polyunsaturated fatty acid. It carries no assigned E-code and is distinct from its omega-3 counterpart, DPAn-3, despite sharing the same carbon chain length.

In nutritional supplement formulation, DPAn-6 serves as a precursor in arachidonic acid metabolism pathways, influencing eicosanoid biosynthesis in targeted infant and clinical nutrition products. In animal feed applications, it is incorporated into aquaculture and livestock diets to modulate tissue fatty acid profiles. Its polyunsaturated structure also contributes antioxidant-related stabilising activity within lipid matrices.

This material is supplied as a liquid fatty acid, typically available in research and commercial grades. Procurement should confirm REACH registration status and supplier-specific certificates of analysis. Packaging formats vary by supplier and order volume; buyers should request documentation aligned with FCC or equivalent food-grade standards where applicable.
