Synthesis of unsaturated fatty acids

Chemistry and Physics of Lipids, 1973
Abstract This article reviews synthetic routes leading to polyunsaturated fatty acids having “skipped” double bonds. Emphasis is placed on the “acetylenic approach”. The suitability of building blocks, their condensation reactions as well as the controlled reduction of triple bonds to cis double bonds are discussed. In addition, the application of

Polymerization of unsaturated fatty acids

Journal of the American Oil Chemists' Society, 1947
SummaryA method is proposed for the preparation of polybasic fat acids or “dimer” acids directly from fatty acids which is readily adaptable to commercial use. The presence of moisture maintained in the reaction vessel by steam pressure substantially prevents decomposition and decarboxylation of the fatty acids.

Unsaturated Fatty Acids in Acne

Archives of Dermatology, 1959
Long-continued, low-fat acne diets often cause weight and energy loss, and resistance to infection may be lowered. Therefore, I decided to give supplemental unsaturated fatty acids to see what the effect would be on the weight loss and on the acne itself.

Oxidation and activation of unsaturated fatty acids

Archives of Biochemistry and Biophysics, 1959
Abstract 1. 1. Small amounts of unsaturated fatty acids are oxidized to CO 2 , both in vivo and in vitro , at a greater rate than the corresponding saturated fatty acids. 2. 2. Fat-feeding to rats stimulates the rate of oxidation of unsaturated fatty acids. 3. 3. Cholesterol-feeding to rabbits, but not to rats, stimulates the oxidation

Board-invited review: Recent advances in biohydrogenation of unsaturated fatty acids within the rumen microbial ecosystem.

Journal of Animal Science, 2008
Recent advances in chromatographic identification of CLA isomers, combined with interest in their possible properties in promoting human health (e.g., cancer prevention, decreased atherosclerosis, improved immune response) and animal performance (e.g ...

Hydroformylation of unsaturated fatty acids

Journal of the American Oil Chemists' Society, 1984
AbstractWhen hydroformylation of unsaturated fatty materials is done with rhodium‐triphenyl phosphine (or phosphite) catalysts, a number of advantages become apparent compared to cobalt carbonyl‐catalyzed reactions. With rhodium, the reaction can be carried out (a) at pressures as low as 200 psi, (b) at each double bond location in a polyunsaturated ...

Camelina sativa cake improved unsaturated fatty acids in ewe's milk.

The Journal of the Science of Food and Agriculture, 2011
BACKGROUND Camelina sativa cake (CSC), a rich source of unsaturated fatty acids, in the case of ruminants, may improve the energy value of a diet and also increase the unsaturated fatty acid content in milk.

Interaction of bisulfite with unsaturated fatty acids

Journal of Toxicology and Environmental Health, 1982
Sodium bisulfite reacted with unsaturated fatty acids, significantly increasing their polarity as determined by behavior on silica gel thin-layer chromatography. The ultraviolet absorption spectra of unsaturated fatty acids (due to the presence of double bonds) were abolished as a result of the reaction. Fatty acids containing more than one double bond

Unsaturated Fatty Acids in Infant Formula

JAMA: The Journal of the American Medical Association, 1978
To the Editor.— I read with great interest the article entitled "The Science of Infant Nutrition and the Art of Infant Feeding" by Calvin W. Woodruff, MD (240:657, 1978). The article is a rather complete review of this matter. I would like, however, to correct a misstatement that appears in the article.

Oxidative decarboxylation of unsaturated fatty acids

, 2011
Long-chain internal olefins were prepared by silver(II)-catalyzed oxidative decarboxylation of unsaturated fatty acids by sodium peroxydisulfate. Similar to saturated carboxylic acids, 1-alkenes were the major decarboxylation product in the additional ...
