A mechanistic study and review of volatile products from peroxidation of unsaturated fatty acids: an aid to understanding the origins of volatile organic compounds from the human body

Journal of Breath Research, 2020
The assessment of volatile compounds (VOCs) for disease diagnosis is a growing area of research. There is a need to provide hard evidence i.e. biochemical routes, to justify putative VOC biomarkers, as in many cases this remains uncertain, which weakens ...

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.

Highly unsaturated fatty acids in nature: what we know and what we need to learn

, 2016
The supply and demand of omega-3 highly unsaturated fatty acids (ω-3 HUFA) in natural ecosystems may lead to resource limitation in a diverse array of animal taxa.

Unsaturated fatty acids promote bioaccessibility and basolateral secretion of carotenoids and α-tocopherol by Caco-2 cells.

Food & Function, 2014
Bioavailability of carotenoids and tocopherols from foods is determined by the efficiency of transfer from food/meal to mixed micelles during digestion, incorporation into chylomicrons for trans-epithelial transport to lymphatic/blood system, and ...

Unsaturated fatty acids, desaturases, and human health.

Journal of Medicinal Food, 2014
With the increasing concern for health and nutrition, dietary fat has attracted considerable attention. The composition of fatty acids in a diet is important since they are associated with major diseases, such as cancers, diabetes, and cardiovascular ...

Transition metal-catalyzed oxidative double bond cleavage of simple and bio-derived alkenes and unsaturated fatty acids

, 2014
The oxidative cleavage of the CC double bond in unsaturated fatty acids into aldehydes or carboxylic acids is a reaction of current interest in biomass valorization. The products of this reaction, which is currently being performed on an industrial scale

Hydrothermal catalytic processing of saturated and unsaturated fatty acids to hydrocarbons with glycerol for in situ hydrogen production

, 2014
Lipids are a promising feedstock to produce renewable hydrocarbon fuels and H2via catalytic hydrothermal processing. Upon exposure to hydrothermal media (e.g., 300 °C, 8–11 MPa), lipids rapidly hydrolyze to produce saturated and unsaturated free 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.
