Fatty acid composition was determined as previously described (Kramer et al., 1997).Fatty acid methyl esters(FAME) were prepared using base-catalysed reactions. Sample aliquots containing 5mg lipids were placed in 15mL glass test tubes with Teflon-lined screw cap, to which 80μL of toluene w...
Thus, using the BF3-methanol reagent, a reaction time of 30 s sufficed for the transesterification of most lipids to their fatty acid methyl esters (FAMEs) with less oxidation of the unsaturated species. Base-catalysed reactions are used extensively for the transesterification of lipids because ...
Designates undecylene Acid ester as the base the deodorant null for the animal fodderThe subject of the invention is a deodorant substance for animal feeds. This substance comprises an undecylenate ester.EME MUNASAANRI KOPAN
;SOLUTION: This curable ester base is a monoester or a polyfunctional ester comprising a mixed fatty acid containing a fatty acid having a conjugated double bond and a polyhydric alcohol. The ratio of a fatty acid residue containing a conjugated double bond in a mixed fatty acid residue linked...
Evidence is presented for the argument that the tertiary nitrogen atom of ceveratrum ester alkaloid derivatives participates in an intramolecular basic catalysis of the solvolysis of C-16 esters, and that the reaction is therefore an instance of intramolecular bifunctional general base-general acid catal...

Fatty acid ethyl estersare minor metabolites of ethanol that are formed after alcohol consumption in virtually all tissues due to interaction of ethanol with free fatty acids as well astriglycerides,lipoproteins, andphospholipids. This pathway is an enzyme-mediatedesterificationof fatty acid or fatty ac...
