, 又称“脑黄金”“聪明因子”
DHA is the abbreviation of Docose Hexaenoie Acid(n22:6),also known as “Brain Gold”“Brightness Gene”
DHA属于Ω-3系列多不饱和脂肪酸是人体必需脂肪酸。
DHA belongs to Ω-3 series polyunsaturated acid, which is essential to our bodies.
人体无法自身合成;需要通过外界摄取,才能获得
It can’t be synthesized by human body and must be absorbed from diet.

在代谢通路上,由 a-亚麻酸转化为 n-3 长链PUFA 的效率逐渐降低
In metabolism, the efficiency of a-linolenic acid into n-3 long-chain PUFA gradually reduced

a-linolenic acid's role is to provide energy rather than a direct biosynthesis of LCPUFAs.
