Oils and fats are substances that are important nutritionally and have important role and impact on human health. Energy consumption and preservation in respect of food industry and the increase in the world population and search for new sources of oils and fats to full fill the need of the society particulary the nutritional requirements have introduced this research topic. Therefore aim of th...

I N A previous report from our laboratories the essential fatty acid requirement of infants was estimated from the polyunsaturated fatty acid composition of the total fatty acids of 1 The same data were used to derive estimation equations whereby the intake of linoleate was determined from polyunsaturated fatty acid analysis of serum. The development of the latter approach was made through anim...

Total fatty acid composition of muscle lipids in some fish species (Cyprinus carpio (Işıklı Dam Lake), Tinca tinca (Işıklı Dam Lake), Scardinius erythrophthalmus (Işıklı Dam Lake), Cyprinus carpio (Karacaören Dam Lake), and Carassius carassius (Karacaören Dam Lake)) was determined by gas chromatography. Polyunsaturated fatty acids (PUFAs) of Cyprinus carpio (Işıklı Dam Lake) were found higher t...

Cells of the diatom Cyclotella meneghiniana were exposed in a closed system to 0.245 ppm 1,2,3-trichlorobenzene. Response of the diatom was measured by quantitative ultrastructure and fatty acid percent composition over a 5-day period. During that time, 35 significant morphological and 12 fatty acid percent composition changes occurred. The most pronounced morphological change that occurred was...

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...
