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 ...

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.

Polyesters ofω-Unsaturated Fatty Acid Derivatives

Macromolecular Chemistry and Physics, 2001
Unsaturated polyesters, based on ω-unsaturated fatty acid esters from oleochemical resources and petrochemical diols, were synthesized via two different synthetic pathways. 9-decenoic and 10-undecenoic acid methyl ester Ia, b were transesterified with petrochemical diols to produce the a,ω-alkylene di(un)decenoates IIa-d, which were subsequently ...

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

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.

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.

Microbial Oxidation of Unsaturated Fatty Acids

1995
Publisher Summary This chapter discusses the oxidation, specifically the hydration, of unsaturated fatty acids. The term “oxidation” defines the addition of oxygen atoms to a substrate (X); the opposite process is reduction. The investigation of the nature of biological oxidation processes eventually proposed a generalized mechanism for biological ...

[Essential unsaturated fatty acids].

Nihon rinsho. Japanese journal of clinical medicine, 1999
Linoleic and alpha-linolenic acids are essential unsaturated fatty acids which were referred to as vitamin F much earlier. Their biological significance is to be converted to eicosapolyenoic acids including arachidonic acid which are the precursors of bioactive eicosanoids such as prostaglandins, thromboxanes and leukotrienes.
