Monk parrots (Myiopsitta monachus) are susceptible to atherosclerosis, a progressive disease characterized by the formation of plaques in the arteries accompanied by underlying chronic inflammation. The family of n-3 fatty acids, especially eicosapentaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA), have consistently been shown to reduce atherosclerotic risk factors ...

The toxic subcellular accumulation of lipids predisposes several human metabolic syndromes including obesity, type 2 diabetes and some forms of neurodegeneration. To identify pathways that prevent lipid-induced cell death, we performed a genome-wide, fatty acid sensitivity screen in Saccharomyces cerevisiae. We identified 160 yeast mutants as sensitive to 0.5 mM ...

As information on free sterols/stanols and steryl/stanyl esters in nuts is lacking, the compositions and contents of these lipid constituents in ten different nut types were analyzed. The applied approach was based on online liquid chromatography-gas chromatography and enabled the simultaneous analysis of free sterols/stanols and individual steryl/stanyl fatty acid ...

Antivenoms are typically produced in horses or sheep and often purified using salt precipitation of immunoglobulins or F(ab')2 fragments. Caprylic (octanoic) acid fractionation of antiserum has the advantage of not precipitating the desired antibodies, thereby avoiding potential degradation that can lead to the formation of aggregates, which may be the ...

yaiW is a previously uncharacterized gene found in enteric bacteria that is of particular interest because it is located adjacent to the sbmA gene, whose bacA ortholog is required for Sinorhizboium meliloti symbiosis and Brucella abortus pathogenesis. We show that yaiW is co-transcribed with sbmA in Escherichia coli and Salmonella ...

Omega-3 (also called n-3) long-chain polyunsaturated fatty acids (≥C20; LC-PUFAs) are of considerable interest, based on clear evidence of dietary health benefits and the concurrent decline of global sources (fish oils). Generating alternative transgenic plant sources of omega-3 LC-PUFAs, i.e. eicosapentaenoic acid (20:5 n-3, EPA) and docosahexaenoic acid (22:6 n-3, ...

Long-chain acyl-CoA synthetase (ACSL; EC 6.2.1.3) catalyzes the conversion of free fatty acid to acyl-CoA ester, which is necessary for many pathways of fatty acid and lipid metabolism. The diatom Phaeodactylum tricornutum genome encodes five putative ACSLs (PtACSL1-5) that contain several highly conserved motifs and share limited sequence similarities with ...

The impact of dietary fatty acids in atherosclerosis development may be partially attributed to their effect on macrophage cholesterol homeostasis. This process is the result of interplay between cholesterol uptake and efflux, which are permeated by inflammation and oxidative stress. Although saturated fatty acids (SAFAs) do not influence cholesterol efflux, ...

The β-acetoacetyl-acyl carrier protein synthase FabY is a key enzyme in the initiation of fatty acid biosynthesis in Pseudomonas aeruginosa. Deletion of fabY results in an increased susceptibility of P. aeruginosa in vitro to a number of antibiotics, including vancomycin and cephalosporins. Because antibiotic susceptibility can be influenced by changes ...

Fatty acids are essential for life because they are essential components of cellular membranes. Lower animals can synthesize all four classes of fatty acids from non-lipid sources, but both omega-6 and omega-3 cannot be synthesized de novo by 'higher' animals and are therefore essential components of their diet. The relationship ...

Postprandial triglyceride-rich lipoproteins (TRLs) are recognized as atherogenic particles whose lipid composition and function can be modified by the composition of dietary oils. This study was designed to test the hypothesis that minor components of pomace olive oil (POMACE) can not only change the composition of postprandial TRL but also ...

Lipoproteins are virulence factors of Mycobacterium tuberculosis. Bacterial lipoproteins are modified by the consecutive action of preprolipoprotein diacylglyceryl transferase (Lgt), prolipoprotein signal peptidase (LspA) and apolipoprotein N- acyltransferase (Lnt) leading to the formation of mature triacylated lipoproteins. Lnt homologues are found in Gram-negative and high GC-rich Gram-positive, but not in ...

Normal fatty aldehyde and alcohol metabolism is essential for epidermal differentiation and function. Long-chain aldehydes are produced by catabolism of several lipids including fatty alcohols, sphingolipids, ether glycerolipids, isoprenoid alcohols and certain aliphatic lipids that undergo α- or ω-oxidation. The fatty aldehyde generated by these pathways is chiefly metabolized to ...

Phospholipid hydrolysis, as the main stage and cause of phopholipid degradation, is generally attributed to phospholipases. In this study, the changes of phospholipase A2 (PLA2) and C (PLC) activities, neutral lipid, free fatty acids and phospholipids in dry-cured duck leg muscles during processing, were examined. The composition of free fatty ...

For several years, in human nutrition there has been a focus on the proportion of unsaturated fatty acids (UFA) and saturated fatty acids (SFA) found in bovine milk. The positive health-related properties of UFA versus SFA have increased the demand for food products with a higher proportion of UFA. To ...

We provide novel insights into the function(s) of β-carotene-15,15'-oxygenase (CMOI) during embryogenesis. By performing in vivo and in vitro experiments, we showed that CMOI influences not only lecithin:retinol acyltransferase but also acyl CoA:retinol acyltransferase reaction in the developing tissues at mid-gestation. In addition, LC/MS lipidomics analysis of the CMOI-/- embryos ...

Two Haptophytes were isolated from extensive aquaculture ponds at Veta La Palma state (Guadalquivir estuary, SW Spain). They were identified as Pseudoisochrysis paradoxa VLP and Diacronema vlkianum VLP based on their SSU rDNA homology to other Haptophytes and positioned in the Isochrysidaceae and Pavlovaceae families, respectively. Both Haptophytes had phosphatidilglycerol ...
