Polyunsaturated hydrocarbons in the stable fly

Journal of Chemical Ecology, 1985
Three triply-unsaturated hydrocarbons were identified from cuticular lipids of male and mixed-sex stable flies,Stomoxys calcitrans. The major compound, (Z,Z)-1,7,13-pentacosatriene, and two minor compounds, (Z,Z)-1,7,13-tetracosatriene and (Z,Z)-1,7,13-tricosatriene, were synthesized.

Polyunsaturated fatty acids of mosquitos reared with single dietary polyunsaturates

Insect Biochemistry, 1987
Abstract Stock adults of Culex pipiens and tarsalis reared in crude media had a third of their phospholipid fatty acids as polyunsaturates, mainly 18C but including prominent proportions of arachidonic (20:4n6) and eicosapentaenoic (20:5n3) acids. Adults reared with synthetic media devoid of polyunsaturated fatty acids and therefore unable to fly at ...

Regioselective amination of polyunsaturated ethers

Tetrahedron, 1992
Abstract (Ethoxycarbonyl)nitrene (NCO2Et) adds selectively to methyl neryl ether, geranyl methyl ether, and allyl neryl ether. For all the substrates the main product (up to 50%) is the aziridine deriving from addition to the double bond remote from the oxygen atom.

Polyunsaturated fatty acids and inflammation

IUBMB Life, 2015
AbstractInflammation is a protective process for life that aims to restore body homeostasis by targeting the injury and by inducing repair mechanisms. This process can also become excessive and lead to chronic inflammation and organ fibrosis. Polyunsaturated fatty acids play a key role in inflammatory processes and their resolution.

Polyunsaturated Fatty Acids

Journal of Gerontological Nursing, 2011
The immune system tends to become less efficient as people age, and nutrition plays a significant role in older adults’ immune responses. In particular, dietary fatty acids are precursors to important immune system components. Certain fatty acids, predominantly those that are polyunsaturated, also tend to decrease the risk of certain neurological ...

Enzymatic Purification of Polyunsaturated Fatty Acids.

Journal of Bioscience and Bioengineering, 2001
Polyunsaturated fatty acids (PUFAs) have various physiological functions. Of these, ethyl eicosapentaenoate is industrially purified and used as a medicine. Other PUFAs, such as docosahexaenoic acid (DHA), gamma-linolenic acid (GLA), and arachidonic acid (AA), are also expected to be used as pharmaceutical agents; however, their industrial purification

The Polyunsaturated Fatty Acids of Microorganisms

1966
Publisher Summary This chapter discusses the polyunsaturated fatty acids of microorganisms. Polyunsaturated or polyenoic fatty acids are those long-chain fatty acids that include two or more double bonds in the molecule. It is widely accepted that bacteria are incapable of synthesizing polyenoic fatty acids, and this generalization applies equally to

Plasmalogens and Polyunsaturated Fatty Acids

2008
The analysis of polyunsaturated fatty acids (“essential fatty acids”) in plasma and erythrocytes is carried out by gas chromatography of their methyl esters following trans-methylation of the fatty acid esters. The O-alkenyl ethers or plasmalogens – an important group of phospholipids – are converted into dimethylacetals in this process and can be ...

The Autoxidation of Polyunsaturated Lipids

1988
The gradual accumulation of oxygen which accompanied the evolution of photosyn-thetic organisms approximately 1.5 billion years ago was most significant in that an appropriate environment had been provided for the genesis of aerobic organisms. Along with the evolution of respiratory organisms emerged a most interesting irony.
