✦ Synopsis

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: I), butter, hydrogenated sunflower oil. It is found that in adipose tissue there are only conjugated dienes whoseconcentration is lower than that of lipids of the respective diets and of the liver. Structural lipids are characterized by a high concentration of conjugated tti-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.
