The degree of incorporation of conjugated dienes, trienes and tetraenes into reserve (depot fats) and structural liver lipids of rats is studied depending on the type of high-fat feeding (50 energy%): lard, lard + sunflower oil (2:1), butter, hydrogenated sunflower oil. It is found that in adipose tissue there are only conjugated dienes whose concentration is lower than that of lipids of the respective diets and of the liver. Structural lipids are characterized by a high concentration of conjugated tri- and tetraenes. It is established that the fatty acid compositions of the diets and their oxidizability coefficients, respectively, do not correlate with the degree of accumulation of conjugated fatty acid structures in living organisms. The disequilibrated high-fat regimens based on butter and partially hydrogenated sunflower oil create conditions for more intensive incorporation of oxidized fatty acid products into the tissues.
研究了大鼠摄入不同类型的高脂饲料（能量占比50%）：猪油、猪油+葵花籽油（2:1）、黄油、氢化葵花籽油后，共轭二烯、三烯和四烯在储备（储存脂肪）和肝脏结构脂质中的掺入程度。结果发现，脂肪组织中仅存在共轭二烯，其浓度低于相应饲料和肝脏脂质中的浓度。结构脂质的特征是共轭三烯和四烯的浓度较高。研究确定，饲料的脂肪酸组成及其氧化系数分别与生物体内共轭脂肪酸结构的积累程度无关。基于黄油和部分氢化葵花籽油的不均衡高脂饮食方案为氧化脂肪酸产物更大量地掺入组织创造了条件。
