Ozone and Unsaturated Fatty Acids
Archives of Environmental Health: An International Journal, 1971The earliest manifestation of the toxicity of ozone in an in vitro system utilizing human erythrocytes had been previously suggested to be due to the breakdown of unsaturated fatty acids in the cell membrane. To confirm that destruction of unsaturated fatty acids does occur in biological membranes exposed to ozone, red cell fatty acids were extracted ...

Synthesis of unsaturated fatty acids
Chemistry and Physics of Lipids, 1973Abstract 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, 1947SummaryA 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, 1959Long-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.

Unsaturated fatty acid metabolism in Neurospora
Archives of Biochemistry and Biophysics, 1953Summary Five independent occurrences of Neurospora mutants requiring unsaturated fatty acids were found. Four of these were allelic and grew in the presence of either oleic, linoleic, or linolenic acid. The remaining mutant which was not allelic was partially blocked in the conversion of linoleic to linolenic acid.

Hydroformylation of unsaturated fatty acids
Journal of the American Oil Chemists' Society, 1984AbstractWhen 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 ...

Oxidation and activation of unsaturated fatty acids
Archives of Biochemistry and Biophysics, 1959Abstract 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

Interaction of bisulfite with unsaturated fatty acids
Journal of Toxicology and Environmental Health, 1982Sodium 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, 1978To 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.
