Biological Activity
All-cis-4,7,10,13,16-Docosapentaenoic acid (all-cis-4,7,10,13,16-DPA) methyl ester, also known as Osbond acid, is an isomer of DPA and a more lipid-soluble variant of the free acid, primarily found in fish oils as an omega-3, 22-carbon fatty acid. Despite being an omega-6 fatty acid synthesized through the elongation and desaturation of arachidonic acid, its levels can decrease due to fatty acid desaturase syndrome, potentially impacting development. Additionally, increased expression of hepatic elongation of very long fatty acids protein 6 and elevated levels of very long-chain fatty acids, including all-cis-4,7,10,13,16-DPA, are indicative of nonalcoholic steatohepatitis, a condition that precedes hepatocellular carcinoma.
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
The structure of compounds is confirmed through HNMR and purity is verified through HPLC or LCMS, with most compounds having a purity of over 98%. Each batch comes with a Certificate of Analysis (COA), and testing reports are also displayed on our official website.
Solid-form products can be stored at -20°C for more than 3 years. Stock solutions are typically stored at -80°C and can be stored for more than 1 year. It is recommended to aliquot the product to avoid repeated freeze-thaw cycles. For short-term storage, samples can be kept at 4°C for more than one week.
