[Title of award-winning research]
Synthesis and functional evaluation of odd-chain polyunsaturated fatty acids

[Details of award-winning research]
　Eicosapentaenoic acid (EPA(20:5n-3)), an n-3 polyunsaturated fatty acid found in abundance specifically in seafood, has the ability to lower blood triglycerides. Furthermore, the beneficial effects of odd-chain fatty acids on various diseases have also been reported in recent years. Therefore, we obtained odd-chain polyunsaturated fatty acids through organic synthesis and evaluated their lipid metabolism-improving effects in cells and animals. As a result, we successfully synthesized an odd-chain polyunsaturated fatty acid with 21 carbon atoms and five double bonds (HPA(21:5n-3)). Furthermore, in cell experiments using HPA, we found that HPA exhibited a stronger inhibitory effect on triglyceride (triacylglycerol) accumulation than EPA. Furthermore, animal studies revealed that HPA also exhibited a stronger inhibitory effect on visceral fat accumulation than EPA.
