The effect of oleic, linoleic and γ-linolenic acids on ROS production by 3T3 Swiss and Rat 1 fibroblasts was investigated. Using lucigenin-amplified chemiluminescence, a dose-dependent increase in extracellular superoxide levels was observed during the treatment of fibroblasts with oleic, linoleic and γ-linolenic acids. ROS production was dependent on the addition of β-NADH or NADPH to the medi...

abstract this experiment was conducted to study the effect of south-west climatic conditions on quantitative and qualitative of fatty acids in dog rose (rosa canina l.) seeds collected from five regions including: semirom (isfahan province), kiar and gerdbishe (charmahal and bakhtiari province), yasuj and meymand (kohgiluye and boyer ahmad province). oil was extracted using soxhlet apparatus; t...

The oxidation rates of lauric, myristic, palmitic, stearic, oleic, alpha-linolenic, linoleic, kappa-linolenic, dihomo-gamma-linolenic and arachidonic acids were studied by use of a radioisotope tracer technique in weanling rats at rest in a metabolism chamber over 24 h. Of the saturated fatty acids, lauric acid (12:0) was the most efficient energy substrate: the longer the chain length of the s...

the effect of kaolin on fruit and oil of olive cv. `zard’ was evaluated in a commercial orchard in fasacity, fars province. mature olive trees cv. `zard’ were sprayed with 0, 3 and 6% kaolin after 60 days, 60and 90 days and 60, 90, 120 days after full bloom. results showed that kaolin concentration and sprayingtime had not significant effects on physicochemical parameters but they had significa...

Shortenings are a mixture of one or more vegetable edible oil with partial hydrogenation in mixed with or without animal fat. In this study, three formulations of shortenings, with the best commercial and technological properties were prepared. Increasing consumption of shortenings at the human daily diet, with low adverse coronary effects in human daily diet, three formulations prepared using ...

Twenty-two genotypes of Brassica (B. rapa, B. juncea, and B. napus) were studied for correlation co-efficient between major fatty acids and path coefficient analysis to partition the cause and effect relationship into direct and indirect components. Correlation coefficient of major fatty acids revealed that significant and positive correlation was between palmitic and oleic acids, palmitic and ...

Hemp seed (Cannabis sativa L.) is rich in many substances beneficial human nutrition, especially proteins, lipids, and total dietary fibre. Contents of these primary metabolites were analysed seeds hemp cultivar Finola grown at three locations Slovakia (Borovce, Vígľaš-Pstruša, Milhostov) within two years (2013, 2014). The average content fibre was 36.10 ± 1.92%, lipids 32.05 0.42%, proteins 24...

The common unsaturated fatty acids present in many vegetable oils (oleic, linoleic and linolenic acids) can be quantitated by 1H-nuclear magnetic resonance spectroscopy (1H-NMR). A key feature is that the signals of the terminal methyl group of linolenic acid are shifted downfield from the corresponding signals in the other fatty acids, permitting their separate integration and quantitation of ...

light, amber and dark colored kernels were rated by eye on a scale of 3 different genotypes (zh1, zh2 and zh3). the oil content was measured using the soxhlet extraction method, ranged from 57.26 to 68.29%, for zh1 (light) and zh2 (amber) respectively. fatty acid compositions were measured using gas chromatography. the main fatty acids were linoleic, oleic and linolenic acids, respectively. als...
