Fatty-acid desaturation and microsomal lipid fatty-acid composition in experimental hyperthyroidism

Lipid content and fatty acid composition in some species of compositae family

Fatty acid desaturation in lung: inhibition by unsaturated fatty acids.

The activity of the enzyme system involved in desaturation of palmitic and stearic acid has been examined in lungs of rats fed fat-free diets supplemented either with 4% safflower oil (controls) or 4% tripalmitin (essential fatty acid (EFA) deficient) both in vivo and in vitro in lung slices. Desaturation, as measured by appearance of 14C-labeled monounsaturated fatty acid in pulmonary total li...

Hepatocyte fatty acid desaturation and polyunsaturated fatty acid composition of liver in salmonids: effects of dietary vegetable oil.

The desaturation and elongation of [1-(14)C]18:3n-3 was investigated in hepatocytes from different populations and three different species of salmonids indigenous to Scotland, brown trout, Atlantic salmon and Arctic charr. Two groups of fish were sampled, before and after they were fed two experimental diets, a control diet containing fish oil and a diet containing vegetable oil (a 1:1 blend of...

Endocrine control of fatty acid desaturation.

Polyunsaturated fatty acids found in animals are fundamental products of successive desaturations and elongations of linoleic ( 18 : 2 , r i 6), a-holenic ( lX:3,ri 3) , oleic ( 18 : 1 , r i 9) and palmitoleic ( 16 : 1 , t i 7) acids. The most important ones are those derived from linoleic and a-linolenic acids and they have major physiological implications. The enzymes responsible for the desa...
