Cardiac lipids (triglycerides and phospholipids) of weanling rats fed diets containing 15% by weight of rapeseed oil (RSO), hydrogenated rapeseed oil (HRSO), trierucin (TE) or tribassidin (TB) were analyzed after 3 and 7 days of feeding. The amount of C22:1 was made equal in the 4 diets. Trans-isomers of erucic acid found in HRSO and TB do not cause as high an accumulation of lipids and docosenoic acids in the heart as erucic acid. Digestibility of brassidic acid (46%) is lower than that or erucic acid (83%) but even then, the amount of brassidic acid found in cardiac lipids (calculated per gram of absorbed fatty acid) after 7 days of feeding is 10 times less than that of erucic acid. Brassidic acid, like erucic acid, can be converted into shorter monoenes (C20:1 and C18:1) since transC18:1 has been found in cardiac phospholipids of rats fed trans-docosenoic acid as the only source of trans-acid in the diet.
在以含15%（重量）菜籽油（RSO）、氢化菜籽油（HRSO）、甘油三芥酸酯（TE）或三巴豆油（TB）的日粮喂养断奶大鼠3天和7天后，分析其心脏脂质（甘油三酯和磷脂）。使4种日粮中的C22:1含量相等。在HRSO和TB中发现的芥酸反式异构体在心脏中引起的脂质和二十二碳烯酸积累量不如芥酸高。油菜酸（46%）的消化率低于芥酸（83%），但即便如此，喂养7天后在心脏脂质中发现的油菜酸量（按每克吸收的脂肪酸计算）比芥酸少10倍。与芥酸一样，油菜酸也可转化为较短的单烯酸（C20:1和C18:1），因为在以反式二十二碳烯酸作为日粮中反式酸唯一来源喂养的大鼠心脏磷脂中发现了反式C18:1。
