在不饱和脂肪酸中,其结构中的第一个不饱和键位于碳键末端倒数第三位者,统称为奥米加(ω)-3脂肪酸。其中结构最简单的α-亚麻酸,来自某些植物的种子中,故被称为“植物性ω-3”。我们日常吃的植物油,如花生油、芝麻油、玉米胚油、葵花籽油、橄榄油等,都极少含或不含有α-亚麻酸;豆油、菜油中
Among the unsaturated fatty acids, the first unsaturated bond in the structure is located at the penultimate position of the carbon bond, collectively referred to as omega (omega) -3 fatty acids. One of the most simple structure of α-linolenic acid, from some plants in the seed, it is called “plant ω-3”. Our daily consumption of vegetable oils, such as peanut oil, sesame oil, corn germ oil, sunflower oil, olive oil, etc., with little or no α-linolenic acid; soybean oil, vegetable oil
