Hydroxy fatty acids of azotobacter agilis

Biochimica et Biophysica Acta (BBA) - Specialized Section on Lipids and Related Subjects, 1963
Abstract Approximately half of the fatty acids recovered after alkaline hydrolysis of the bound lipid of Azotobacter agilis were hydroxy acids. The hydroxy acids were isolated by gas-liquid chromatography and were identified as 3-hydroxydecanoic, 3-hydroxydodecanoic and 2-hydroxydodecanoic acids by the retention volume of the methyl ester in gas ...

α-Hydroxy fatty acids in sphingolipids of tetrahymena

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1972
Abstract Sphingolipids of Tetrahymena pyriformis W were found to contain six major fatty acids: the saturated fatty acids 16:0 (n), 17:0 (i), and 18:0 (n), as well as the α-hydroxy fatty acids which have the same three carbon skeletons and presumably are derived from the saturated fatty acids. The structures of the α-hydroxy fatty acids were proven

Hydroxy Fatty Acid Metabolism in Brain

1968
Publisher Summary This chapter discusses the biosynthesis metabolism of hydroxy fatty acid (HFA) in brain. While a great variety of chain lengths is to be found in the HFA of other animal tissues, the assortment in brain is rather limited. Cerebronic acid (h24:0) is by far the main acid, with h22:0 and h24:l next, and h23:0, h25:l, and h26:l next in ...

Analysis of lipids containing hydroxy fatty acids

Lipids, 1987
AbstractLipids containing hydroxy fatty acids or hydroxyacyl moieties are acetylated with [1‐14C]acetic anhydride or [3H]acetic anhydride, and the content of hydroxy fatty acids or hydroxyacyl moieties is estimated from the specific radioactivity of the acetylated products with respect to that of radioactive standards, such as radioacetylated ...

Glucosylation of aroma chemicals and hydroxy fatty acids

Journal of Biotechnology, 2015
To explore the utility of glycosyltransferases as novel biocatalysts, we isolated the glycosyltransferase genes CaUGT2 and SbUGTA1 from Catharanthus roseus and Starmerella bombicola, respectively and heterologously expressed them in Escherichia coli. The purified recombinant proteins were assayed with a variety of small molecule substrates.

Hydroxy long-chain fatty acids in fungi

World Journal of Microbiology & Biotechnology, 1994
Hydroxy long-chain fatty acids occur widely in animals and plants and have important physiological activities in these eukaryotes. There are indications that these compounds are also common and important in fungi. The occurrence of hydroxy-polyunsaturated fatty acids (hydroxy-PUFAs) is of biotechnological importance, because these compounds are ...

The identification of hydroxy fatty acids in psoriatic skin

Prostaglandins, 1983
Psoriasis is a common chronic inflammatory and proliferative skin disease characterised by epidermal neutrophil infiltration which may be induced by chemotactic substances in the involved epidermis. Superficial psoriatic scale was shown to contain biologically active amounts of leukotriene B4 and monohydroxy-eicosatetraenoic acid (HETE)-like material ...

Reaction of fatty acids with hydroxy-radicals

Journal of the Chemical Society C: Organic, 1968
In the presence of hydroxy-radicals, palmitic, oleic, and linoleic acids are partially transformed into the corresponding C2n–2 hydrocarbon and a Cn–1 alcohol. The double bonds in unsaturated acids may be preserved by performing the reaction in a heterogeneous system.

Hydroxy fatty acids in the surface Earth system

Science of The Total Environment
Lipids are ubiquitous and highly abundant in a wide range of organisms and have been found in various types of environmental media. These molecules play a crucial role as organic tracers by providing a chemical perspective on viewing the material world, as well as offering a wealth of information on metabolic activities.

Glycosides of Hydroxy Fatty Acids

1990
Hydroxy fatty acid glycosides are probably the least well known of all the glycolipids, certainly less so than any of the other glycolipids discussed in this volume. They never seem to have been mentioned in any textbooks on lipid biochemistry. The other, better known glycolipids, also composed of sugars and hydroxy fatty acids, are those in which the ...
