Investigation of the chemical composition of the essential oils from subterranean organs (S) of Nephrolepis cordifolia (NC) and Nephrolepis exaltata (NE) (F. Lomariopsidaceae) grown in Egypt was carried out. Gas Chromatography/mass Spectrometry (GC/MS) analysis of the hydro-distilled NCS and NES oils revealed that oxygenated compounds were abundant, being 55.35% and 33.85%, respectively. Ethyl ...

the glass transition temperature of several pvac(1)-b-poly(ma-co-mma) (2) terpolymers with different fractions of methyl acrylate (ma) and methyl methacrylate (mma) repeating units in random copolymer (block 2) were calculated with barton, kwei and topological equations. the calculation was on the basis of the correlation between the fraction of repeating units in random copolymers and theoreti...

We investigated the fatty acid composition of the phospholipid fraction of the shoulder muscle (triceps brachii) from Jersey and Limousin yearling steers, yearling heifers, and nonlactating cows. The aim was to study breed, sex, and age differences. Significant breed differences in some individual fatty acids were apparent between Jersey and Limousin cows. Limousin cows had more palmitate, vacc...

Background: The production of waste pollutants has become a major problem for many food and oil industries. However, oil wastes can provide alternative substrates for industry, which could help to solve environmental pollution problems. Furthermore, oil wastes can be used as substrates to produce unsaturated fatty acids, which are important for health. Objectives: The production of fatty acids ...

Supplements of purified fatty acid methyl or ethyl esters were fed at levels of 0.8’% of dietary calories to each of seven groups of weanling rats for a period of 60 days. The esters were 9,12-octadecadienoate (18 :2) ; 9,12,15-octadecatrienoate (18:3); 10,13-nonadecadienoate (19:2); 5,8,11,14eicosatetraenoate (20 :4) ; 5,8,11,14,17 eicosapentaenoate (20:5)i 4,7,10,13,16,19-docosahexaenoate (22...

octanoate or decanoate per mol of albumin caused a decrease in dye binding (dye/protein molar ratio 1 : 1), which, in contrast with additional fatty acid, was very pronounced: 1-8mol of palmitate or stearate resulted in a small, and apparently linear, displacement of Phenol Red. The displacement effect of 1-5 mol of oleate, linoleate or linolenate per mol of albumin was comparable with that of ...
