BACKGROUND/AIMS Accumulating evidence has suggested that free fatty acids (FFAs) interact with protein kinases and protein phosphatases. The present study examined the effect of FFAs on protein phosphatases and Akt. METHODS Activities of protein phosphatase 1 (PP1), protein phosphatase 2A (PP2A), and protein tyrosine phosphatase 1B (PTP1B) were assayed under the cell-free conditions. Phosphor...

Modifications in dietary fatty acid intake might lead to a modification in membrane phospholipid fatty acid composition. The purpose of this study was to investigate relationship between different type of oil consumption and leukocyte membrane phospholipid composition. This study was carried out in subjects utilizing butter (n = 15), margarine (n = 15), fluid oil (n = 15) and mixed types of oil...

Peanut, a high-oil crop with about 50% oil content, is either crushed for oil or used as edible products. Fatty acid composition determines the oil quality which has high relevance to consumer health, flavor, and shelf life of commercial products. In addition to the major fatty acids, oleic acid (C18:1) and linoleic acid (C18:2) accounting for about 80% of peanut oil, the six other fatty acids ...

Gangliosides were isolated from human, bovine, and rabbit plasma and were quantified by gas-liquid chromatography. Purification was achieved by sequential use of partitioning in solvents, DEAE-Sephadex chromatography, base treatment, and silicic acid chromatography. Human and bovine plasma yielded slightly more than 1 micro mole of lipid-bound sialic acid/100 ml; for rabbit plasma the value was...

Abstract Intensive fat deposition is accompanied by an increased synthesis of saturated and monounsaturated fatty acids, resulting in a decrease the proportion polyunsaturated acids muscle tissue. The TG5 (c.-422C >T) polymorphism associated with metabolism Bos Taurus. aim research was to study effect on acid composition tissue Hereford bulls. Polymorphism analyzed polymerase chain react...

The pine nuts, as the most expensive ones, are a source of healthy oil. Accordingly, the hypothesis was genetic differences of pine species (Pinus spp.) affect their nut oil content and fatty acid phytovariability. A completely randomized design experiment with three replicates was done in Isfahan Flower Garden, Iran, using four pine species of chir pine (Pinus longifolia<...

Abstract Background To compare plasma fatty acids (FAs) between participants with primary open-angle glaucoma (POAG) and without neuropathy in an elderly population to investigate specific FAs pattern POAG. Methods We conducted a population-based study older than 75 years. Participants underwent comprehensive eye examination optic nerve photographs, visual field test OCT RNFL thickness measurem...

The excess biomass of drifting algae and their casting to the Baltic Sea coast imposes a significant environmental burden. analysis beach-cast showed that dominant species are macroalgae Ulva sp., Furcellaria lumbricalis, Cladophora Polysiphonia fucoides. algae, containing 25.6% 19.98% sugars, respectively, has greatest resource potential in terms obtaining carbohydrates. Fucose, glucose, galac...

BACKGROUND The aim of our work was to compare two methods, both based on direct transmethylation with different reagents, BF3/MeOH (boron trifluoride in methanol) or HCl/MeOH (hydrochloride acid in methanol), in acid catalysis, without prior extraction, to find the fast, non-expensive but enough precise method for 9 principal fatty acids (lauric, myristic, palmitic, stearic, oleic, linoleic, li...
