The absorption of [14C]linoleic acid and [14C]stearic acid in guinea pig bile by the in situ guinea pig gallbladder was compared. Linoleic acid was adsorbed at a faster rate than was stearic acid. Differences were also observed in the incorporation of these two fatty acids into complex lipids of the gallbladder mucosa. A greater portion of adsorbed linoleic acid was incorporated into triacylgly...

Essential oils of two wild-growing Artemisia species collected from west of Iran during the flowering stage were obtained by hydro-distillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC–MS). Under the optimum extraction and analysis conditions, 23 and 19 constituents were identified in A. fragrans and A. hausskenechtii which represented 92.96% and 90.2...

The aim of our work was to compare cytotoxic and membrane-damaging effects of O. majorana L. essential oil and linalool on Hep G2 and to investigate their possible protective (antioxidant) effects against H2O2 induced membrane damage. The oils were investigated by GC and GC-MS and antioxidant activity was evaluated by DPPH and -carotene–linoleic acid assays. Assessment of cell viability was ma...

Over the course of the twentieth century, there was a 20-fold increase in consumption of vegetable oils resulting both from their increased availability and from recommendations to consume these oils as an aid to lower blood cholesterol levels. This dietary change markedly increased the consumption of linoleic acid to current levels of approximately 6% of total dietary energy. While considerabl...

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...

The linoleic acid content of serum lipids was measured in 47 patients with multiple sclerosis, 29 patients with other neurological diseases, 35 patients with acute non-neurological illnesses, and 49 healthy control subjects. Reduced linoleic acid content of serum lipids was not specific to multiple sclerosis and occurred in all ill patients with acute non-neurological illness. The fatty-acid pa...

In this research work, a series of heterocyclic Schiff base compounds bearing arylsulfonyl ester moiety (2a-i) were designed, synthesized, characterized by spectral techniques such as 1D NMR (1H and 13C), 2D (COSY HMQC), FT-IR; then examined their antioxidant activity was using four different methods DPPH, ABTS, CUPRAC, ?-carotenelinoleic acid assays. According to the results obtained, it deter...

The effects of monosomy of specific chromosomes on the fatty acid composition of maize embryos were studied. A novel technique was developed to obtain fatty acid profiles of single embryos without reducing the viability of the sampled kernels. Monosomic 2 embryos had significantly more oleic acid and significantly less linoleic acid than diploid control embryos. Since the conversion of oleic ac...

The objective of this study was to compare the effects of linoleic acid (cis,cis-C18:2(n-6)) and its hydrogenation products elaidic (trans-C18:1(n-9)) and stearic acid (C18:0) on serum lipoprotein levels in humans. Twenty-six men and 30 women, all normolipemic and apparently healthy, completed the trial. Three experimental diets were supplied to every subject for 3 weeks each, in random order (...
