Increased content of very-long-chain fatty acids in the lipids of halophyte vegetative organs
It was shown that the vegetative organs of higher plants not subjected to genetic transformation, such a high VLCFA content was found for the first time, and the roots exceeded severalfold the above-ground organs in the total V LCFA content.
Distribution of unusual fatty acids in the triacylglycerols of sea buckthorn mesocarp oil
The structure of unusual fatty acid (FA) components of triacylglycerols (TAGs) of mature sea buckthorn (Hippophae rhamnoides L.) mesocarp oil was determined by GLC and MS, and the positional-species
Seasonal dynamics of fatty acids in the lipids of water moss Fontinalis antipyretica from the Yenisei River
Identification of lipid fatty acids (FA) and studying of their seasonal dynamics in water moss Fontinalis antipyretica from the Yenisei River were carried out by means of gas chromatography-mass
The fatty acid profile of Serbian bee-collected pollen – a chemotaxonomic and nutritional approach
The fatty acid profile, its relation to botanical origin and nutritional characteristics of bee-collected pollen from Serbia was determined and the most abundant saturated, mono- and poly unsaturated fatty acids were palmitic, oleic and linolenic acid, respectively.
Cistus ladanifer L. Shrub is Rich in Saturated and Branched Chain Fatty Acids and their Concentration Increases in the Mediterranean Dry Season
Marked seasonal changes in BCFA and polyunsaturated fatty acids (PUFA) were found, suggesting that BCFA can replace PUFA in plant lipids at high environmental temperatures.
Demospongic Acids Revisited
The Δ5,9 fatty acids appear to be a particular type of non-methylene-interrupted fatty acids (NMA FAs), which have also been observed in various marine sources with a large range of chain-lengths and from some terrestrial plants with short acyl chains.
Fatty and Volatile Oils of the Gypsywort Lycopus europaeus L. and the Gaussian-Like Distribution of its Wax Alkanes
The detailed analyses of the volatile essential oil and lipid profiles of the aerial parts from the blooming and fruit-forming stages of both ripe and unripe fruit of Lycopus europaeus (Lamiaceae)
Structural diversity and possible functional roles of free fatty acids of the novel soil isolate Streptomyces sp. NP10
The results suggest that the free FAs produced by Streptomyces NP10 could have an ecophysiological role in interspecies signaling with another soil microorganism Pseudomonas aeruginosa, and could be useful in microbial biodiesel production.
anteiso-Fatty Acids in Brussels Sprouts (Brassica oleracea var. gemmifera L.): Quantities, Enantioselectivities, and Stable Carbon Isotope Ratios.
Selective enrichment followed by enantioselective gas chromatography with mass spectrometry in the selected ion monitoring mode revealed that both a15:0 and a17:0 were (S)-enantiopure in Brussels sprout samples.
Stearidonic acid (18:4n‐3): Metabolism, nutritional importance, medical uses and natural sources
This work reviews the nutritional significance, medical uses and natural occurrence of SA, and suggests that vegetable oils containing SA may become a dietary source of n-3 fatty acids that is more effective in increasing tissue n- 3 PUFA concentrations than the current ALA-containing vegetable oils.


The unusual occurrence of 14-methylhexadecanoic acid in pinaceae seed oils among plants
It is concluded that Pinaceae, along with Ginkgo biloba seed lipids, are major exceptions in the plant kingdom with regard to 14-MHD acid, which otherwise occurs almost exclusively in lipids of animals and microorganisms.
Fatty Acid Composition of Mitochondrial Membrane Lipids in Cultivated (Zea mays) and Wild (Elymus sibiricus) Grasses
A high level of ω3-desaturase activity in the mitochondrial membranes seems to be an important factor of elymus chilling tolerance, and appears to be developed as an adaptation in the course of evolution of this species.
Isovaleric acid as a precursor of odd numbered iso fatty acids in Tetrahymena
The methyl esters of the saturated fatty acids obtained from the polar lipids by alkaline methanolysis were separated by reversed phase chromatography, the identities confirmed by gas chromatography-mass spectrometry, and the specific activities determined.
Fatty acid composition of seed oils of the meliaceae, including one genus rich incis-vaccenic acid
The seed lipids of three species ofEntandraphragma (Meliaceae) contain the largest proportion (31–50%) ofcis-vaccenic acid ever found in nature. The acid is not indicative of the family as a whole
On the Control of Fatty Acid Compositions of Plant Glycerolipids
Just a few years ago, there were sufficient clues to suggest that the problem of fatty acid distribution within plant glycerolipids might be soluble.
Seed oils of Nigella species and of closely related genera
The seed oil fatty acid fingerprints obtained from all the Nigella species show that 20: 2n-6 was the largest peak of the C 20 fatty acids group, i.e. the peak height ratios of 20:1 to 20:2 were reversed from those in most normal vegetable oils.
