Unsaturated fatty acids of mycobacteria

Lipids, 1970
AbstractThe double bond locations have been determined for the mono‐unsaturated fatty acids, C14 to C26 ofM. smegmatis andM. bovis BCG. The 14∶1 and 16∶1 fatty acids fromM. smegmatis are principally Δ10, while the 17∶1, 18∶1 and 19∶1 fatty acids from both organisms are Δ9. In the case ofM.

Ozone and Unsaturated Fatty Acids

Archives of Environmental Health: An International Journal, 1971
The 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 ...

Conversion of unsaturated fatty acids - cycloadditions with unsaturated fatty acids [1]

Lipid - Fett, 1998
Diels-Alder reactions with methyl conjuenate (2) at room temperature, with methyl E-12-oxo-10-octadecenoate (11) as dienophile and radical cation catalyzed cycloadditions of 2 are described. 2 is prepared from methyl linoleate by base catalyzed isomerization with sodium dimethylsulfoxide in 90% yield.

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.

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

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

Chemistry and Biochemistry of Unsaturated Fatty Acids

Angewandte Chemie International Edition in English, 1976
AbstractAlthough unsaturated fatty acids have long been known to accompany saturated fatty acids in most lipids, qualitative and quantitative determination of fatty acid patterns only became possible with the advent of modern analytical methods. Present day knowledge of the chemical structure, physical properties, and metabolism of unsaturated fatty ...

Unsaturated fatty acid metabolism in Neurospora

Archives of Biochemistry and Biophysics, 1953
Summary 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.
