DPA (Docosapentaenoic Acid, 22:5n-3)

<p><strong><span lang="EN-US">Abstract</span></strong></p> <p><span lang="EN-US">Docosapentaenoic acid (DPA, 22:5n-3) is a long-chain omega-3 fatty acid located metabolically between EPA and DHA, yet possessing unique and irreplaceable physiological functions. </span></p> <p><span lang="EN-US">Unlike EPA or DHA, DPA demonstrates experimentally validated angiogenic activity through VEGF upregulation and endothelial progenitor cell (EPC) mobilization, enabling vascular repair and microcirculatory regeneration. <br>It exerts potent anti-thrombotic effects by integrating into platelet membranes and inhibiting aggregation, reducing thrombosis risk without impairing coagulation. </span></p> <p><span lang="EN-US">DPA also generates exclusive pro-resolving lipid mediators (RvDPA series, protectins), providing dual action in inflammation resolution and tissue repair. <br>Beyond vascular health, DPA plays a critical role in male fertility by stabilizing sperm membrane integrity and mitochondrial function, and it enhances reverse cholesterol transport (RCT) through ABCA1/ABCG1 activation, thereby promoting lipid clearance and anti-atherosclerotic effects. </span></p> <p><span lang="EN-US">Emerging evidence suggests DPA further contributes to female hormonal balance, endometrial remodeling, and preconception support. </span></p> <p><span lang="EN-US">Clinically, DPA shows particular value in populations with hypertension, diabetes-related microvascular impairment, post-cardiovascular interventions, chronic inflammation, elderly vascular aging, metabolic dysfunction, and reproductive health challenges. </span></p> <p><span lang="EN-US">Despite its low dietary abundance, DPA serves as a “small but mighty” bioactive omega-3 fatty acid with broad applications across cardiovascular, metabolic, reproductive, and inflammatory domains.</span></p>
