The fatty acid composition of Morris Hepatoma 7777 cells was modified by exposure to culture media that were supplemented with 0.1 to 0.36 mM oleic or linoleic acid for 5 days. Changes occurred in the fatty acid composition of both the cellular phospholipid and the neutral lipid fractions. Exposure to linoleic acid caused a large increase in the polyunsaturated fatty acid content of the cell li...

The bovine fatty acid desaturase (FADS) gene cluster consists of FADS1, FADS2, FADS3, and FADS6, which acts as key enzymes in fatty acid metabolism. Of these, the genetics effects of variants in FADS1, FADS2 and FADS3 have been previously studied. However, the genetic effects of variants of FADS6 gene have not been studied. The aim of this study was to identify genetic variants in the bovine fa...

The study was conducted to study the effect of age viz., young (6-9 months) and adult (2 years) on physico-chemical characteristics, proximate composition, amino acid, fatty acid and cholesterol content of Kodiadu goat meat. The Longissimus dorsi muscle was collected from these animals and the physico-chemical characteristics viz., pH, water holding capacity, instrumental colour, muscle fi bre ...

A literature review was made of the influence of nutritional factors on the fatty acid composition of fat deposits and muscles of lambs. A bibliographic data base, containing 979 observations from 108 papers, was made up in such way that one observation corresponded to one group of lambs in one experiment. Each nutritional factor was studied only when number of observations was sufficient. Cons...

Changing the milk fatty acid composition can improve the nutritional and physical properties of dairy products and their acceptability to consumers. A more healthful milk fatty acid composition can be achieved by altering the cow's diet, for example, by feeding supplemental fish oil (FO) or roasted soybeans (RSB), or by selecting cows with a more unsaturated milk fatty acid composition. We exam...

Dietary fatty acid composition, particularly polyunsaturated fatty acids, can affect both genetic and non-genetic regulatory mechanisms of carnitine palmitoyltransferase (CPT) I, the main regulatory enzyme of mitochondrial fatty acid oxidation. We aimed to determine how these regulatory mechanisms were affected by changes in the fatty acid composition of the diet in fish. Specifically, we fed r...

Sphingomyelin, ceramide, cerebroside, and cerebroside sulfate from beef brain were isolated by column chromatography in quantitative yield and in pure form. The fatty acid composition of each sphingolipid was determined by gas-liquid chromatography (GLC). Sphingomyelin contained only nonhydroxy fatty acids, while cerebroside, cerebroside sulfate, and ceramide contained both nonhydroxy and hydro...

in detail by many investigators.'-6> The difference in the amount of secreted surface lipid by sex and by age was also reported repeatedly.7-17) The difference of fatty acid composition of human skin surface film lipid by sex and by age was first examined by Boughton and Wheatley 41 According to these investigators, the skin surface lipids from the same subject varied little from time to time, ...

The content of fatty acids as well as the ratio between unsaturated and saturated fatty acids is important parameter for determination of nutritional value of certain oil. Therefore the newest trend in food processing industry is notifying the composition of edible oils and other food commodities for the content of each individual fatty acid. The main objective of this work was to identify the ...
