We studied fatty acids (FAs) profiles in six carotenoid-producing yeast species isolated from temperate aquatic environments in Patagonia. Total FAs ranged from 2 to 15% of dry biomass. Linoleic, oleic, palmitic and alpha-linolenic acids were the major FAs constituents, which accounted for as much as 40%, 34%, 13% and 9% of total FAs, respectively. The proportion of each FA varied markedly depe...

In order to study the effects of saturated fatty acids on ∆6-desaturase activity, rat hepatocytes in primary culture were incubated with lauric (C12:0), myristic (C14:0) or palmitic (C16:0) acids. After optimization, the standard in vitro conditions for the measurement of ∆6desaturase activity were as follows: 60 μmol·L–1 α-linolenic acid (C18:3n-3), reaction time of 20 min and protein content ...

Research work was carried out to investigate the physicochemical analysis of olive oil extracted from olives grown in Khyber pakhtunkhwa. The samples were studied for physicochemical characteristics (Specific gravity, refractive index, Acid value, Saponification value and Peroxide value). The free fatty acidity is thus a direct measure of the quality of the oil. Olive oil was analysed for fatty...

A better understanding of the inhibitory and and linolenic acids on pneumococci at a concenstimulating effects of fatty acids on the growth of tration of 40 ppm, whereas 200 ppm exerted a microorgankisms may contribute to a clearer bactericidal influence. Streptococci were someappreciation of some general nutritional probwhat more resistant; according to Walker (82) lems, such as: they were inh...

Seedlings of wheat were grown for 24 h in control nutrient solution and in solutions containing haloxyfop, alloxydim, diquat or paraquat, and thereafter the roots were used for microsomal preparations. Phosphatidylcholine or diacylglycerol with various 1-(14)C-labelled fatty acids (oleic, linoleic, linolenic or ricinoleic acids) in position sn-2 were added to the prepared microsomes. After incu...

BACKGROUND Oleic acid is the principal fatty acid of olive oil composition and is reported to play a crucial role in its healthy aspects. However, the detailed mechanism of action is poorly understood. AIMS This study aims to elucidate the role of oleic acid in calcium signaling in rat thymocytes, in comparison to linoleic and linolenic acid. METHODS Fatty acids were applied to thymocytes i...

Abstract Background Rhodotorula toruloides is a robust producer of triacylglycerol owing to its fast growth rate and strong metabolic flux under conditions high cell density fermentation. However, the molecular basis fatty acid biosynthesis, desaturation regulation remains elusive. Results We present characterization four desaturase (FAD) genes in R. . Biosynthesis oleic (OA) palmitoleic (POA) ...

Recently, there has been a great deal of attention on usage, byproducts, and wastes of the food industry. There have been many studies on the properties of citrus seeds and extracted oil from citrus grown in Kerman, Iran. The rate of oil content of citrus seeds varies between 33.4% and 41.9%. Linoleic acid (33.2% to 36.3%) is the key fatty acid found in citrus seeds oil and oleic (24.8% to 29.3...

Gottlieb, David (University of Illinois, Urbana), and James L. Van Etten. Changes in fungi with age. I. Chemical composition of Rhizoctonia solani and Sclerotium bataticola. J. Bacteriol. 91:161-168. 1966.-The chemical composition of the mycelium of Rhizoctonia solani and Sclerotium bataticola was determined in cells of various ages. The percentage, per unit of dry weight, of soluble amino nitr...

Here, we assessed the effects of long-chain fatty acids (LCFAs) and the LCFA receptor agonist GW9508 on the transcription of the gonadotropin subunit genes Cga, Lhb and Fshb because LCFA receptor GPR120 was observed in mouse gonadotropes in our recent study. A transcription assay using LβT2 cells demonstrated that LCFAs, oleic acid, α-linolenic acid, docosahexaenoic acid and palmitate, represse...
