FREE FATTY ACIDS IN ANIMAL TISSUES

Occurrence of 2-hydroxy Fatty Acids in Animal Tissues.

Free fatty acids in an animal model of Reye's syndrome.

Recent studies have indicated that viral infections, aspirin treatment and hyperammonemia are associated with Reye's syndrome. It has also been reported that free fatty acids in serum and total lipids in the liver of Reye's syndrome patients are elevated during illness. The role of the lipid changes in the development of the disorder cannot be optimally studied in human patients, because infect...

Determination of nucleic acids in animal tissues.

As reported in a previous paper (l), a new microchemical method for the determination of deoxyribonucleic acid (DNA) has been devised which permits the evaluation of DNA in amounts as small as 2.5 y per ml. The method is particularly useful with very small quantities of tissue. For this reason a study was undertaken to learn the best conditions for the application of the method to the determina...

High Free Fatty Acids

Biodiesel is an alternative fuel for diesel engines consisting of the alkyl monoesters of fatty acids from vegetable oils or animal fats. Most of the biodiesel that is currently made uses soybean oil, methanol, and an alkaline catalyst. The high value of soybean oil as a food product makes production of a cost–effective fuel very challenging. However, there are large amounts of low–cost oils an...

Sulfonated porous carbon catalyzed esterification of free fatty acids

The esterification of free fatty acids (FFA) with methanol is studied using Sulfonated Porous Carbon (SPC) as catalyst. In compare to the amorphous sugar catalyst and protonated Nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. The highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol H+ and mole ra...
