The influence of long duration rapeseed oil feeding with high or low levels of erucic acid has been investigated on rat heart phospholipids. The rats treated for 20 wk with rapeseed oil containing 46.2% erucic acid showed a twofold increase in the sphingomyelin content of the heart. Treatment with
The comparative rates of oxidation of erucic and oleic acids and of their CoA esters were studied in heart and liver mitochondria of rats fed a standard diet or semisynthetic diets containing 25% of the calories as either rapeseed oil (46.6% erucic and 10.4% eicosenoic acid) or olive oil, for a
1. The metabolism of [14(-14)C]erucic acid and [U-14C]palmitic acid was studied in perfused hearts from rats fed diets containing hydrogenated marine oil, rapeseed oil or peanut oil for three weeks. 2. [14C]Erucic acid was shortened to [14C]eicosenoic acid (20 : 1, n -- 9) and [14C]oleic acid (18 :
The effect of clofibrate on heart and plasma lipids in rats fed a diet containing 30% of the calories as peanut oil (PO) or rapeseed oil (RSO) (42.7% erucic acid and 0.5% eicosenoic acid) was studied. A decrease of erucic acid content to one-third and concomitant increase in the content of 18:1,
Fully refined rapeseed oil, Brassica campestris var. Arlo plus Echo, and corn oil were fed at 20% by weight of a basal diet to young Yorkshire boars. A serial slaughter technique was employed whereby 3 boars from each dietary treatment were killed at 0,1,2,3,4 and 8 weeks of the experiment. The
Boars fed diets containing rapeseed oil for 8 weeks showed significantly higher levels of neutral lipids and similar levels of phospholipids, compared to those fed corn oil. Erucic and eicosenoic acids were found to be high in ethanolamine phosphoglycerides, and in particular alkenyl
Experiments were conducted to compare energy utilization, growth and tissue composition of chicks fed diets containing 10 or 20 parts of either high erucic acid rapeseed oir 24 days. Results showed that chicks fed diets containing 10 or 20 parts LER grew at the same rate, utilized energy just as
Weanling SPF male rats were fed for 12 weeks purified diets containing by weight 15 p. 100 sunflower oil, high erucic acid rapeseed oil or low erucic acid rapeseed oil. During the same period of time they were subjected to a moderate treadmill-running program and compared with sedentary animals fed
1. In chicks fed rations containing 15% rapeseed oil (RSO) or soybean oil (SBO) a gradual increase in the lipid content of heart tissue was found from 1 to 10 days of age. The finding that feeding high levels of RSO to chicks did not cause excessive accumulation of fat in cardiac tissue supports the
A total of 384 male Single Comb White Leghorn chicks of the Hyline strain were randomized in 24 Petersime battery units of 16 birds per unit. Four replicate pens were fed either a basal (control) diet containing no added oil or a diet supplemented with 20% by weight of either soybean oil or rapeseed
In this study, an analytical method for the detection and identification of extra virgin olive oil adulteration with four types of oils (corn, peanut, rapeseed, and sunflower oils) was proposed. The variables under evaluation included 22 fatty acids and 6 other significant parameters (the ratio of
Seed-specifically expressed beta-ketoacyl-CoA synthase genes of Brassica napus (Bn-FAE1.1 genes) were cloned from two cultivars, namely Askari, a high-erucic-acid type, and Drakkar, a low-erucic-acid type. The genes from the two cultivars were found to be nearly identical. They encode proteins of
