To study the effect of salicylic acid (SA) on the amount and quality of oil in different regions of sunflower inflorescence, a factorial experiment was conducted based on randomized complete block design with 3 replications at the University of Mohaghegh Ardabili, Ardabil, Iran. Salicylic acid at concentrations of 0, 0.1, and 0.2 g L-1 were sprayed on whole plant at 3 stages (twice before flowe...

The aim of the investigation was to determine the changes in fatty acids profile and chemical quality indexes of Red Tilapia fillets during frozen storage at -18°C. The fish were filleted by hand. The prepared fillets were then placed to the polyamide pouches and stored at -18°C for 150 days. Fatty acid profile, sensory properties and chemical quality indices were determined for a five month pe...

Accumulation of free unsaturated fatty acids, added individually to the medium, into cellular triacylglycerol (TG) were examined using a fungus, Mucor hiemalis HA-30, which could produce the eicosapentaenoic acid (20:5n-3)-enriched TG. Linoleic (18:2n-6), γ-linolenic (18:3n-6), arachidonic acids (20:4n-6), and 20:5n-3 were favored for accumulation in TG and each fatty acid accumulated in TG at ...

An analysis of the phospholipid ester-linked and the lipopolysaccharide (LPS) fatty acids and hydroxy fatty acids of six lactate-utilizing Desulfovibrio-type sulfate-reducing bacteria (SRB) has been performed using capillary gas-liquid chromatography-mass spectrometry (GLC-MS). The concentrations of normal fatty acids were essentially similar, with the possible exception of a high content of no...

Dietary lipid composition profoundly influences the hibernation pattern of the chipmunk Eutamias amoenus. The object of the present study was to investigate whether these physiological changes following feeding of saturated and unsaturated lipids were associated by compositional changes of fatty acids of tissues and membranes. Animals were fed with rodent chow (control diet), rodent chow with 1...

The effect of fatty acids with various structure and length in the hydrocarbon chain on the purified AMP deaminase from bovine brain was investigated. All the saturated fatty acids and unsaturated ones of trans configuration, longer than 16 in the hydrocarbon chain, were activators of the enzyme, while the unsaturated fatty acids of cis configuration including oleic, linoleic, linolenic, arachi...
