A linoleic acid enriched diet increases serum cholesterol esterification by lecithin:cholesterol acyltransferase in meal-fed rats.

Dietary fats are known to influence the fatty acid profile of plasma lipids, including phospholipids which are substrates of lecithin:cholesterol acyltransferase (LCAT; EC 2.3.1.

The influence of a fish oil-enriched diet on the phospholipid fatty acid turnover in the rabbit red cell membrane in vivo.

The influence of the polyunsaturated fatty acid (PUFA) composition of the diet on the rate of fatty acid turnover of individual phospholipids in the erythrocyte membrane in vivo was studied. Following modification of the fatty acid composition of the membrane phospholipids by the use of a fish oil or a linoleic acid enriched diet, phospholipids--labelled in the unsaturated fatty acid at the 2-position of the glycerol moiety--were introduced into the membrane of freshly isolated rabbit erythrocytes. Thereafter, the labelled erythrocytes were reinjected into the bloodstream of the animal.

Dietary non-tocopherol antioxidants present in extra virgin olive oil increase the resistance of low density lipoproteins to oxidation in rabbits.

Consumption of a range of dietary antioxidants may be beneficial in protecting low density lipoprotein (LDL) against oxidative modification, as studies have demonstrated that antioxidants other than vitamin E may also function against oxidation of LDL in vitro. In the present study, the effect of polyphenol antioxidants on the susceptibility of LDL to copper-mediated oxidation was investigated after feeding semi-purified diets to 3 groups of New Zealand white (NZW) rabbits. All diets comprised 40% energy as fat with 17% energy as oleic acid.

Comparison of the effects of dietary vitamin E on in vivo and in vitro parameters of lipid peroxidation in the rabbit.

This study has investigated the effect of dietary vitamin E on markers of antioxidant status. Four groups of rabbits received diets containing 30 energy percent (en%) total fat (7.8 en% contributed by linoleic acid) for 12 weeks.

Positional distribution of stearic acid and oleic acid in a triacylglycerol and dietary calcium concentration determines the apparent absorption of these fatty acids in rats.

In this study the effect of the positional distribution of stearic acid (18:0) and oleic acid (18:1) in a triacylglycerol on absorption of fat, energy and nutrients was investigated in young rats. In addition the effect of dietary calcium on these variables was studied. Forty rats were fed purified diets containing either a fat blend high in 2-oleoyl-distearate or a fat blend high in 1-oleoyl-distearate.
