反式脂肪酸(trans fatty acids,TFA)是不饱和脂肪酸的一种,是所有含反式非共轭双键的不饱和脂肪酸的总称,因其与双键相连的氢原子分布在碳链的两侧而得名。反式脂肪酸虽然也属于不饱和脂肪酸,但反式双键的存在使脂肪酸的空间构型产生了很大的变化,脂肪酸分子呈刚性结构,性质接 Trans fatty acids (TFA) is a kind of unsaturated fatty acid, which is the general term of all unsaturated fatty acids containing trans non-conjugated double bonds. Because of the distribution of hydrogen atoms in the carbon chain Side named. Although trans-fatty acids are also unsaturated fatty acids, the existence of trans-double bonds has greatly changed the spatial configuration of fatty acids. The fatty acid molecules have a rigid structure.
