OBJECTIVE Elovl6, a long-chain fatty acid elongase, is a rate-limiting enzyme that elongates saturated and monounsaturated fatty acids and has been shown to be related to obesity-induced insulin resistance via modification of fatty acid composition. In this study, we investigated the roles of Elovl6 in foam cell formation in macrophages and atherosclerosis in mice. METHODS AND RESULTS To inve...
To facilitate the study of adrenoreceptor response in small needle biopsy samples of human subcutaneous adipose tissue, we developed a dual radioisotopic technique for measuring lipolysis rate. Aliquots (20-75 mg) of adipose tissue fragments were incubated in a buffered albumin medium containing [3H]palmitate and [14C]glucose, each of high specific activity. In neutral glycerides synthesized in...
Hydrophobically modified xylo-oligosaccharides were prepared by enzymatic esterification of xylo-oligosaccharide and three fatty acids: decanoic acid (C-10), lauric acid (C-12) and palmitic acid (C-16). Lipase obtained from Thermomyces lanuginosus was used as a biocatalyst in the reaction. The degree of substitution (DS) of esterified xylo-oligosaccharide, prepared at a reaction temperature of ...
BACKGROUND Marine derived oils are rich in long-chain polyunsaturated omega-3 fatty acids, in particular eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have long been associated with health promoting effects such as reduced plasma lipid levels and anti-inflammatory effects. Krill oil (KO) is a novel marine oil on the market and is also rich in EPA and DHA, but the fatty acids...
Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt-60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P<0.0.5) were found between non-irradiated and irradiated sea bass in terms of moisture, protein, fat,...
Carotenoids and their fatty acid esters in the carapace of the spiny lobster Panulirus japonicus were investigated. Fatty acid esters of astaxanthin, adonixanthin, and pectenolone were characterized by (1)H-NMR and FAB-MS. The acylated position of adonixanthin and pectenolone monoesters was determined to be a hydroxy group at C-3' by (1)H-NMR. The fatty acids esterified with these carotenoids w...
The neutral lipids of Acholeplasma axanthum contain carotenoid pigments, as evidenced by spectral characteristics, visual color, color reactions, and labeling with [2-14C-A1mevalonic acid. Approximately 80% of the label from [2-14C]mevalonic acid appeared in esterified fatty acids of the glycolipids and polar lipids. These carboxylic acids behaved as hydroxy acids of varying chain length.
