Effect of dietary fats on endogenous oleic acid biosynthesis in rat liver

چکیده
Aim: Determine the effect of dietary fats with different fatty acid composition on biosynthesis oleic and its metabolic precursors in liver .
 Methods: High linoleic sunflower oil (HLSO), high (HOSO) palm (PO) were used. Rats fed a semi-synthetic fat-free diet (FFD) fat diets containing 5 % above oils (instead starch) for 30 days. Liver lipids divided into 3 fractions: neutral (NL), phospholipids (PL) free acids (FFA). The fractions was determined by gas chromatography. “activity” synthase from total content products this reaction (C16:0 C16:1). palmitic elongase ratio С18:0/С16:0, as well formula (С18:0+С18:1)/(С16:0–С16:1). stearic desaturase (SCD1) C16:1/C16:0 (SCD16) C18:1/C18:0 (SCD18).
 Results: In rats treated diets, is reduced only NL fraction, to greatest extent when consuming HLSO. increases significantly consumption SCD16 decreases diet, while SCD18 increases. level higher than SCD16. Consumption HLSO reduces ω-3 PUFA rat lipids, intake HOSO it.
 Conclusions: endogenous acids, analysis fraction. A but “activity”, especially HOSO. lipids.

The effect of different dietary fats on liver fat deposition.
When weanling rats are fed a ration containing 9 per cent casein with sucrose as the carbohydrate and with an adequate supply of the known lipotropic factors, fatty infiltration of the liver occurs (1, 2). The addition of 0.36 per cent of nn-threonine to the diet causes a considerable decrease in liver fat deposition but does not reduce the liver fat content to as low a level as is found in rat...

The effects of two oleic-acid-rich diets (containing olive oil, OO, and high-oleic-acid sunflower oil, HOSO) on plasma and liver lipid composition detoxification enzyme activities, were compared with those of a fish-oil (FO) diet and a control diet. Compared with the control diet, plasma and hepatic total triacylglycerol concentrations were increased in the animals fed on the HOSO and OO diets ...

The minimum dietary intake of oleic acid that is indispensable to maintain a normal content of this fatty acid in several tissues (heart, muscle, kidney and testis) was determined in the rat. For this purpose, a dose-effect study was conducted using an experimental protocol with 7 groups of rats who received a diet in which the oleic acid level varied from 0 to 6000 mg per 100 g diet, but the o...

1. The liver ribosomes of rats given cycloheximide by intraperitoneal injection incorporate less amino acid into protein than ribosomes from control rat liver when they are incubated in vitro with excess of Sephadex-treated cell sap. The effect is rapid, marked and persistent. 2. Cell sap from liver of cycloheximide-treated animals is inhibitory but the inhibition can be relieved almost entirel...
