反式脂肪酸(trans fatty acid,TFA)是一类不饱和脂肪酸,其双键上2个碳原子结合的2个氢原子分别在碳链的两侧,空间构象呈线形。自然界中天然存在的TFA由反刍动物厌氧菌产生,从而进入食物链;TFA也可在植物或鱼油的加工氢化过程中形成。TFA的大量存在可在一定程度上降低细胞膜的通
Trans fatty acid (TFA) is a class of unsaturated fatty acids whose two hydrogen atoms bonded by two carbon atoms on their double bonds have linear spatial conformations on both sides of the carbon chain. Naturally occurring TFA is produced by ruminant anaerobes to enter the food chain; TFA can also be formed during the process of plant or fish oil hydrogenation. A large number of TFA can reduce the cell membrane through to a certain extent
