Biological activity
| Bioactivity | Heneicosapentaenoic Acid (HPA) is a 21:5 omega-3 fatty acid found in trace amounts in the green alga B. pennata and in fish oils. Its chemical composition is similar to eicosapentaenoic acid (EPA), except that a carbon is extended at the carboxy terminus, placing the first double bond at the δ6 position. HPA can be used to study the importance of double bond position in omega-3 fatty acids. It incorporates phospholipids and triacylglycerols in vivo with the same efficiency as EPA and docosahexaenoic acid, and exhibits a strong inhibitory effect on the synthesis of arachidonic acid from linoleic acid. HPA is a poor substrate for prostaglandin H synthase (PGHS) (cyclooxygenase) and 5-lipoxygenase, but retains the ability to rapidly inactivate PGHS. |

Information
| Intro | Heneicosapentaenoic Acid (HPA) 是一种 21:5 ω-3 脂肪酸，微量存在于绿藻 B. pennata 和鱼油中。它的化学组成与二十碳五烯酸 (EPA) 相似，只是在羧基端加长了一个碳，将第一个双键置于 δ6 位。 HPA 可用于研究 ω-3 脂肪酸中双键位置的重要性。它以与 EPA 和二十二碳六烯酸相同的效率在体内掺入磷脂和三酰甘油，并表现出对从亚油酸合成花生四烯酸的强烈抑制作用。 HPA 是前列腺素 H 合酶 (PGHS)（环氧合酶）和 5-脂氧合酶的不良底物，但保留了快速灭活 PGHS 的能力。 |
