必需脂肪酸 Essential fatty acid(重定向自Essential fatty acid deficiency)
必需脂肪酸(英语:Essential fatty acid;缩写EFA)是指人体内(或其他高等动物)不能自行合成、但又必须从食物中获得的脂肪酸。 只有两种脂肪酸是是人体必需的:亚油酸(一种ω-6双不饱和脂肪酸)和α-亚麻酸(一种ω-3三不饱和脂肪酸)。其它脂肪酸均可以由这两种为原料逐步合成。哺乳动物无法合成这两种脂肪酸是因为去饱和酶能力有限,有四种去饱和酶分别在靠近羧基的ω-9、ω-12、ω-15、ω-18位引入双键,但不能在靠近碳链末端的ω-3、ω-6位引入双键所致;不过植物细胞没有这个限制。 1923年两种必需脂肪酸被发现时,原本叫作维生素F,以表示它是人体必须养份,但1930年的研究认为它们的形态更像脂肪,因而出现现有的学名。

Essential fatty acid 必需脂肪酸(重定向自Essential fatty acid deficiency)
Essential fatty acids, or EFAs, are fatty acids that humans and other animals must ingest because the body requires them for good health but cannot synthesize them. The term "essential fatty acid" refers to fatty acids required for biological processes but does not include the fats that only act as fuel. Essential fatty acids should not be confused with essential oils, which are "essential" in the sense of being a concentrated essence. |
