Some marine algae can form volatile aldehydes such as n-hexanal, hexenals, and nonenals. In higher plants it is well established that these short-chain aldehydes are formed from C18 fatty acids via actions of lipoxygenase and fatty acid hydroperoxide lyase, however, the biosynthetic pathway in marine algae has not been fully established yet. A brown alga, Laminaria angustata, forms relatively h...

Seventy-two pregnant ewes were al lot ted to three ration t reatment groups: 1) Control: corn silage and alfalfa pellets; 2) Tallow: corn silage, alfalfa pellets and protected tallow; 3) Polyunsaturated (P/S): corn silage and protected soybean and sunflower seeds. Diet influenced plasma glucose and linoleic acid content of esterified, but not of non-esterified, fat ty acids in ewe plasma. Propo...

This paper focused on the assessment of antioxidant property and fatty acid composition of four Centaurea species. The antioxidant activity of its methanol extract was evaluated by several in vitro experiments including phosphomolybedum assay, DPPH assay, β-carotene/linoleic acid, ferric and cupric reducing power. Total phenolic and flavonoid contents were also evaluated. The methanol extract o...

Linoleic acid is the fatty acid under which the omega-6 fatty acids, a type of ?good fat [2]?, are categorized. Conjugated linoleic acid (CLA), on the other hand, has the same molecular formula as linoleic acid but a different chemical structure. These essential nutrients aren?t produced by the human body and therefore must be ingested from plantand animal-based food products, such as vegetable...

Mammalian cells can metabolize linoleic acid (C,8:2, , , , , ) by A-6-desaturation to y-linoleic acid (C18:3,,,-,,), which can be elongated to dihomo-y-linoleic acid (C211.3,,z, ), and subsequently undergo A-5-desaturation to arachidonic acid (AA) (C211:J,rr-,,) 11 I . Most freshwater fish are also capable o f this process 121, whereas marine species such as turbot (Scopthulmirs maximus) appare...

BACKGROUND Substitution of dietary polyunsaturated for saturated fat has long been recommended for the primary prevention of cardiovascular disease (CVD), but only a few prospective cohort studies have provided support for this advice. METHODS We assessed the association of dietary linoleic and total polyunsaturated fatty acid (PUFA) intake with cardiovascular and overall mortality in a popul...

Oxidative modification of low density lipoprotein has been suggested as patho-physiologically relevant process in atherogenesis and the lipid peroxidizing enzyme 15-lipoxygenase may be involved. For experimental evidence on the in vivo action of this enzyme in the time course of plaque formation we analyzed the lipid extracts of lesional areas representing various stages of human atherogenesis ...

OBJECTIVE To test the hypothesis that the essential fatty acid, linoleic acid, measured in adipose tissue as an indicator of long term dietary intake, is inversely related to the risk of sudden cardiac death. DESIGN A population case-control study. SETTING A regional health district. SUBJECTS 84 men (age 25-64 years) who died instantaneously or within 24 hours of the onset of symptoms wit...

The hepatic carcinogen N-2-fluorenylacetamide (2-acetylaminofluorene) was shown previously to interact specifically with its target protein, liver fatty acid binding protein (L-FABP), early during hepatocarcinogenesis in rats. In search of the significance of the interaction, rat L-FABP cDNA in the sense and antisense orientations was transfected into a subline of the rat hepatoma HTC cell line...
