BACKGROUND Ergosterol has been considered the "fungal sterol" for almost 125 years; however, additional sterol data superimposed on a recent molecular phylogeny of kingdom Fungi reveals a different and more complex situation. METHODOLOGY/PRINCIPAL FINDINGS The interpretation of sterol distribution data in a modern phylogenetic context indicates that there(More)
Several strains of species of the fungal genus Pythium, and of Phytophthora cinnamomi, were screened for content of the polyunsaturated fatty acids (PUFAs) arachidonic acid (AA) and eicosapentaenoic acid (EPA). The aim of the investigation was to establish alternative sources of these PUFAs, which are of importance in human nutrition. As a relatively(More)
This study was conducted to determine if dietary omega-3 polyunsaturated fatty acids could modulate lung eicosanoid production. Three groups of chickens were depleted of essential fatty acids by feeding diets containing 1% hydrogenated coconut oil from hatching to 8 wk, followed by repletion for 3 wk with diets containing soybean oil (SBO) and linseed oil(More)
As a representative of a genus with species considered to be potential commercial producers of the nutritionally important polyunsaturated fatty acid docosahexaenoic acid (DHA), Thraustochytrium sp. ATCC 26185 was investigated to determine its potential for DHA production and lipid composition. Cells from liquid shake cultures contained 32% (w/w) lipid, 18%(More)
The freely extractable sterols of spores ofLinderina pennispora, Spicaria elegans, Penicillium claviforme, Aspergillus niger, Ustilago nuda, U. maydis, Puccinia graminis, andP. striiformis were examined using mass spectrometric techniques. Each species contained at least 3–5 detectable sterol components in the 4-desmethyl sterol fraction, and, when present,(More)
The lipids of Rhizopus arrhizus Fischer mycelia and sporangiospores were extracted, isolated, and separated by thin-layer, liquid, and gas chromatography. Structural confirmations of the compounds were made by a gas chromatographmass spectrometer combination. The n-heptane fraction contained squalene (1%) as a major hydrocarbon constituent. Other major(More)
A new series of lipids called mololipids have been identified from an Hawaiian sponge of the order Verongida. The structures of these lipids was deduced from spectroscopic data of the lipid mixture combined with GC-MS analysis. The core of this novel series of lipids is a bromotyramine homoserine-derived moiety known as moloka'iamine (1) which is found in(More)
Multilamellar lipid vesicles (MLV) composed of egg yolk lecithin (EYL) suppressed the response of bovine peripheral blood lymphocytes (BPBL) to phytohemagglutinin (PHA). EYL contains 18:1 and 18:2 as the major unsaturated phospholipids. Dioleoyllecithin (DOL; cis 9) MLV did not suppress BPBL blastogenesis. Dilinoeyllecithin (DLL; cis, cis 9, 12) MLV(More)
