Influence of consumption of high oleic sunflower oil on the biosynthesis of fatty acids in the liver of rats

Background. To determine the effect of consumption high-oleic sunflower oil on content and biosynthesis energy polyunsaturated (PUFA) fatty acids in rat liver lipids.
 Methods. Rats received a semi-synthetic fat-free diet which 5 % or 15 starch was replaced with high oleic oil. One group rats regular (high linoleic) The duration feeding 30 days. Liver lipids were divided into three fractions: neutral lipids, phospholipids free acids, acid composition determined by gas chromatography. "activity" synthase, palmitic elongase, stearyl-CoA desaturase (SCD18) ratio content.
 Results. It found that largest amount (60-80 %) are (C16:0 + C16:1 C18:0 C18:1). PUFA account for 10-30% all they also fed free-fat (FFD). Fatty diets reduce but increase elongase desaturase. A linoleic reduces ω-3 while increases it dose-dependently. containing dose-dependently (SCD16). Consumption sharply ω-6/ω-3
