Heneicosapentaenoic acid
Biochemical Assay Reagent
Heneicosapentaenoic Acid (HPA) is a 21:5 omega-3 fatty acid primarily known for its role as a biochemical assay reagent. It is structurally similar to eicosapentaenoic acid (EPA) but has an additional carbon at the carboxy terminus, resulting in a distinct double bond positioning at the δ6 position. HPA facilitates research into the significance of double bond positions in omega-3 fatty acids and effectively incorporates into phospholipids and triacylglycerols. Additionally, it demonstrates a strong inhibitory effect on arachidonic acid synthesis from linoleic acid while inactivating prostaglandin H synthase, offering valuable insights into lipid metabolism and inflammation pathways.
