SUMMARY A comparison has been made of the metabolism of l-C'4-labeled oleic, elaidic, palmitic, and stearic acids in the rat. Each acid was fed as a component of randomly rearranged soybean oil. All the acids were more than 96% absorbed. The rate of catabolism and the extent to which elaidic acid was ex-creted in the respiratory CO, were essentially the same as those of oleic acid and both of these acids were similar to pal-mitic acid. Oleic, elaidic, and palmitic acids were catabolized to COZ… Expand
β-Oxidation of the coenzyme a esters of elaidic, oleic, and stearic acids and their full-cycle intermediates by rat heart mitochondria
beta-Oxidation rates for the CoA esters of elaidic, oleic and stearic acids and their full-cycle beta-oxidation intermediates and for the carnitine esters of oleic and elaidic acids were comparedExpand
Dissimilar Properties of Vaccenic Versus Elaidic Acid in β-Oxidation Activities and Gene Regulation in Rat Liver Cells
TLDR
The position and geometry of the double bonds in acyl chains are suggested to confer on vaccenic and elaidic acid specific biochemical properties that might differently affect their fates in tissues. Expand
Vaccenic and Elaidic Acid Equally Esterify into Triacylglycerols, but Differently into Phospholipids of Fed Rat Liver Cells
TLDR
On the whole, vaccenic and elaidic acid were shown to incorporate cell phospholipids unequally, at least in vitro, which suggests they can differently affect lipid metabolic pathways in normal cells. Expand
Incorporation of [10-14C] Oleic Acid or [10-14C] Elaidic Acid into Lipids of Liver, Adrenal and Plasma Lipoproteins of Normal and Essential Fatty Acid-Deficient Rats
Abstract Incorporation of [10- 14 C] oleic acid or [10- ,4 C] elaidic acid into tissue lipids by rats was studied 4 h after the intubation of labelled compounds. The animals were prefed 10% fat dietsExpand
A comparison of the metabolism of geometrical isomers of 14 C- 9 -octadecenoic acid in threonine-imbalanced rats.
TLDR
14C-elaidicacid was given to animals prefed threonine-imbalanced diets containing elaidinized olive oil and initially was incorporated into liver phospholipids and low density lipoproteins to a much greater extent than oleic acid. Expand
INCORPORATION AND METABOLISM OF THE DIETARY TRANS‐UNSATURATED FATTY ACID, ELAIDIC ACID, BY DEVELOPING RAT BRAIN 1

Trans‐unsaturated fatty acids, geometrical isomers of naturally occurring cis‐acids, are dietary components and are incorporated into complex lipids of many tissues. There is little information aboutExpand
Wax esters in fish: Turnover of oleic acid in wax esters and triglycerides of gouramis
TLDR
The biological half life of 18∶1 in gouramis is estimated to be about four months, equal for males and females although translocation from roe to body and transformation of wax ester to triglyceride take place in the female, whereas wax esters do not play any role in the lipid metabolism of the male. Expand
Differential oxidation of saturated and unsaturated fatty acids in vivo in the rat.
The oxidation rates of lauric, myristic, palmitic, stearic, oleic, alpha-linolenic, linoleic, kappa-linolenic, dihomo-gamma-linolenic and arachidonic acids were studied by use of a radioisotopeExpand
The effect of chain length on the activation and subsequent incorporation of fatty acids into glycerides by the small intestinal mucosa.
TLDR
A modification of the hydroxamic acid method for determining acyl-CoA synthetase suggested that the specificity of the enzymes studied contributes to the partition of fatty acids between portal blood and chyle during fat absorption. Expand
Metabolism of polyglycerol and polyglycerol esters.
TLDR
Hydlysis experiments in vitro confirmed that the oleic acid ester bond in the G3 and G10 esters was readily cleaved, as is the same bond in triglycerides, which would explain why more of the label from this compound than from oleate was detected in the feces and gastrointestinal contents. Expand
