Regulatory effects of individual n-6 and n-3 polyunsaturated fatty acids on LDL transport in the rat

Journal of Lipid Research, 1993
Dietary triglycerides containing predominantly poly-unsaturated fatty acids (PUFAs) are known to reduce plasma total and low density lipoprotein (LDL) cholesterol concentrations relative to triglycerides containing predominantly saturated fatty acids ...

Fatty acid profiles in marine and freshwater fish from fish markets in northeastern Poland

Archives of Polish Fisheries, 2014
The fatty acid compositions were studied in eight commercially important fish from fish markets: salmon, Salmo salar L.; cod, Gadus morhua L.; common sole, Solea solea (L.); European flounder, Platichthys flesus (L.); catfish, Clarias gariepinus ...

Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]

arXiv, 2006
The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each

Meta‐regression of the relationship between dietary 18C n‐3 concentration and enrichment of n‐3 fatty acids in liver and breast muscle of broiler chickens

Lipids, EarlyView.
Abstract The long‐chain n‐3 fatty acids (FA) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have human health benefits, and many experiments have investigated the ability of plant n‐3 sources to enrich n‐3 FA in broiler meat. A meta‐regression was conducted to evaluate the relationship between dietary 18‐carbon n‐3 FA content and the ...

Modification of spleen phospholipid fatty acid composition by dietary fish oil and by n-3 fatty acid ethyl esters

Journal of Lipid Research, 1993
We have compared the effects of diets containing purified ethyl esters of either eicosapentaenoic acid, docosahexaenoic acid, or a mixture of both of these compounds, with diets containing either purified fish oil or beef tallow on spleen phospholipid ...

The Factors of the Classification of Protein Amino Acids [PDF]

This paper is published in GLASNIK of Montenegrin Academy of Science and arts, 2000, 13, pp. 173-194, 2006
In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).

Catabolism of leukotriene B5 in humans

Journal of Lipid Research, 1990
Human neutrophils, enriched by dietary supplementation with eicosapentaenoic acid, form leukotriene (LT)B5 in addition to LTB4 upon stimulation. LTB5 is one order of magnitude less biologically active than the potent chemokinetic and chemoattractant LTB4.

Modeling of the formation of short-chain acids in propane flames [PDF]

arXiv, 2009
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

Discovery Of Copper Catalyst For New Chemical Polishing Acid On Superconducting Niobium [PDF]

arXiv, 2020
High field Q-slope (HFQS) seriously limits the high gradient performance of the buffered chemically polished (BCP) superconducting radio frequency (SRF) niobium cavities. The direct cause or mechanism is not yet fully understood. In our recent extensive data analysis, we concluded that the potential root cause could be nitrogen contamination on the ...

A thermodynamic basis for prebiotic amino acid synthesis and the nature of the first genetic code [PDF]

, 2009
Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites.
