Autoxidation of the fatty acids. 3. The oily products from elaidic and oleic acids. The formation of monoacyl derivatives of dihydroxystearic acid and of alphabeta-unsaturated keto acids.
In Part 1 (Ellis, 1932) it was shown that finely dispersed elaidic and oleic acids, when exposed to oxygen at temperatures of about 650, showed an uptake of over 20% by weight in a few hours. About one-fifth of this oxygen was evolved as carbon dioxide and an appreciable but uncertain amount of water vapour was also given off. In Part 2 (Ellis, 1936) it was shown that the main crystalline produ...
متن کاملA comparison of the metabolism of elaidic, oleic, palmitic, and stearic acids in the rat.
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 t...
متن کاملOxidation of oleic and elaidic acids in rat and human heart homogenates.
Parallel incubations with uniformly 14C-labeled oleic and elaidic acids were conducted to compare oxidation rates in tissue homogenates prepared from rat and human hearts. Radioactivity in 14CO2 and 14C-labeled chain-shortened acid-soluble products was used to measure the extent of oxidation. Oxidation rates (pmol/min per mg heart protein) determined on 14C-labeled acid-soluble products suggest...
متن کاملDetermination of Tocopherols and Fatty Acids in Seeds of
Background: The dried fruits of Silybum marianum (L.) Gaertn (Compositae) contain silymarin, an isomeric mixture of flavonolignans. Silymarin acts as a strong anti -hepatotoxic. This fruits contains a high amount of oil . Objective: The objective of this study was to determine total lipid content, fatty acid composition and content of different kind of tocopherols in seed oils of S. marianum...
متن کاملEffects of oleic acid and its congeners, elaidic and stearic acids, on the structural properties of phosphatidylethanolamine membranes.
Fatty acid derivatives are abundant in biological membranes, mainly as components of phospholipids and cholesterol esters. Their presence, free or bound to phospholipids, modulates the lipid membrane behavior. The present study shows the differential influence of the C-18 fatty acids (FAs), oleic, elaidic, and stearic acids on the structural properties of phosphatidylethanolamine (PE). X-ray di...
