A comparative study was conducted to see the mutational analysis for monounsaturated fatty acids in rapeseed (Brassica napus L.) mutant populations. By using gamma irradiation, a range of variability generated for oil content and fatty acid composition in rapeseed seeds. The induced genetic variability was analyzed for two consecutive years in two contrasting environments at elevations of 510 a...

The thiourea isoxyl (thiocarlide; 4,4'-diisoamyloxydiphenylthiourea) is known to be an effective anti-tuberculosis drug, active against a range of multidrug-resistant strains of Mycobacterium tuberculosis and has been used clinically. Little was known of its mode of action. We now demonstrate that isoxyl results in a dose-dependent decrease in the synthesis of oleic and, consequently, tuberculo...

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 oleic acid-ozone heterogeneous reaction system: products, kinetics, secondary chemistry, and atmospheric implications of a model system – a review J. Zahardis and G. A.

The binding of oleic acid to human serum albumin causes progressive changes in (a) the pK of some amino acid residues, as detected by pH-stat titration and (b) the induced molar ellipticities of albumin-bound drugs (diazepam and oxyphenbutazone), as measured by c.d. It is concluded that albumin undergoes several conformational transitions as the amount of oleic acid bound increases from 0 to ab...

This experimental study aimed to compare the adsorption of oleic acid (fatty acid) by two adsorbent; activated carbon and carbon nanotube by use of Uv-Vis spectrophotometer Jenway 6505 model. In this study, five different concentrations of oleic acid in the range of 282.47ppm to 847.41ppm were used. In all conducted experiments, the values of adsorbents, exposure time, temperature, and pH were ...

Linoleic, oleic, and stearic fatty acids, presented vapor-phase retronasally, were discriminable from blanks and each other, but the same concentrations, oral-cavity-only (OCO), were not discriminable from blanks. It remained possible that higher concentrations might be discriminable OCO. To evaluate this, participants attempted to discriminate undiluted linoleic, oleic, or stearic acids, vapor...

Although lipids are essential nutrients in the mammalian diet, we have shown that fatty acids are injurious to epithelial cells of developing piglet intestine during luminal perfusion. Furthermore, the intestine of young animals sustains greater injury than that of older piglets. In an effort to understand the mechanism for this developmental injury, we investigated whether changes in the chemi...

The effects of lauric acid (C12:0) on plasma lipids and lipoproteins were compared with the effects of palmitic acid (C16:0) and oleic acid (C18:1) in a metabolic-diet study of 14 men by using liquid-formula diets fed for 3 wk each in random order. Lauric acid was supplied in a synthetic high-lauric oil, palmitic acid was provided by palm oil and oleic acid in oleic-rich sunflower seed oil. The...

The long-chain 18-carbon fatty acids linoleic, oleic, and stearic acids, retronasally in vapor phase, are discriminated from blanks and each other. However, ability to linguistically identify them was unknown. To explore this, a Focus Group and then Check-All-That-Apply measures gave 9 identifiers for the 3 fatty acids plus phenylethyl alcohol (PEA) and geraniol. Next, participants selected 1 o...
