Autoxidation of Unsaturated Fatty Acid Methyl Esters. I.
Journal of Japan Oil Chemists' Society, 1978 Methyl linoleate and its trans, trans isomer, methyl linolenate, and a mixture of methyl eicosapentaenoate and methyl docosahexaenoate (50 : 50%) were autoxidized in the conditions free from natural antioxidants and metals. Their autoxidations gave the induction period of 49, 52, 18 and 11h, and showed the oxidation rates of 3.61, 3.08, 5.24 and 9.41 ...

Tritioboration and synthesis of tritium-labeled polyunsaturated fatty acids
Journal of Lipid Research, 1969 Methyl esters of polyunsaturated fatty acids labeled with tritium were prepared by partial stereoselective reduction of the corresponding acetylenic esters with tritiated disiamylborane, followed by protonolysis with tritiated acetic acid.

The influence of exogenous cholesterol on hepatic lipid composition of the rat*
Journal of Lipid Research, 1962 Rats were fed diets containing cottonseed oil and/or cholesterol, cholic acid, methyl esters of long-chain fatty acids, and tocopherol. Livers, hearts, and aortas were examined histologically; liver lipids were fractionated by silicic acid chromatography;

Novel strategy of using methyl esters as slow release methanol source during lipase expression by mut+ Pichia pastoris X33. [PDF]
PLoS ONE, 2014 One of the major issues with heterologous production of proteins in Pichia pastoris X33 under AOX1 promoter is repeated methanol induction. To obviate repeated methanol induction, methyl esters were used as a slow release source of methanol in lipase ...

Opportunities for the Development of The Oleochemical Industry of Coconut Products [PDF]
E3S Web of Conferences, 2022 Coconut commodities that have been processed into copra or oil are less strategic to develop because they compete with palm oil and other vegetable oils such as soybean oil, sunflower nuts. As a result, the price of coconut oil, although the upward trend,
