[Dynamics of the fatty acid composition of lipids in biological fluids of dogs].

Fatty acid composition of various lipids was studied in dog blood plasma from femoral and portal veins as well as in dog lymph from thoracic duct and intestinal tract under conditions of acute experiments. Reverse dynamics of the saturation patterns i.e. the ratio of total saturated and unsaturated fatty acid radicals, was found for cholesterol esters and phospholipids from the lymph of intestinal tract and thoracic duct. More than 3-fold reduction of cholesterol esters saturation in the lymph of thoracic duct depended on an increase in linoleates and oleinates. The data obtained suggest that the active transformation of lipids in the lymphatic system is a results of lecithin-cholesterol-acyltransferase effect.
