Medium-chain fatty acid synthesis.
Most plant and mammalian tissue lipids contain fatty acids with a carbon chain longer than 14 atoms. However, milk lipids from several species like ruminants and rodents (Jenness, 1974), seed lipids from certain plants like coconuts (Child, 1974) and Cuphea (Graham & Kleiman, 1985) and lipids from several insects (AddaeMensah & Cameron, 1978) and from some bird glands (Downing, 1976; Jacob, 197...
متن کاملLong-chain fatty acid determination
You, J., X. Zhao, Y. Suo, Y. Li, H. Wang, and G. Chen, Determination of LongChain Fatty Acids in Bryophyte Plant Extracts by HPLC with Fluorescence Detection and Identification with MS, J. Chromatogr. B 848:283–291, 2007. A sensitive method has been developed for the determination of long-chain fatty acids (LCFAs) (>C20) using 1-[2-(ptoluenesulfonate)-ethyl]-2-phenylimidazole-[4,5-f]-9,10-phena...
متن کاملKinetic Investigation of Enzymatic Synthesis of Sucrose Fatty Acid Esters from Sucrose and Non-edible Rice Bran Fatty Acid
Enzymatic synthesis of sugar fatty acid esters were performed in an organic solvent using Immobilized Rhizomucor miehei (RMIM) lipase with sucrose and non-edible rice bran fatty acid as substrates. The maximum conversion of sucrose esters up to 78% obtained when sucrose and non-edible rice bran fatty acid were reacted in molar ratio of 1:8, using n-butanol as a solvent and 1% molecular sieves w...
متن کاملDetermination of ganglioside non-hydroxy fatty acid and long chain base by analysis of perbenzoylated derivatives.
The non-hydroxy fatty acid and long chain base compositions from as little as 2.7 nmol of ganglioside were ascertained from perbenzoylated ganglioside derivatives. Non-hydroxy fatty acids were determined by mild alkaline methanolysis of the derivatives, followed by gas-liquid chromatography (GLC) of the methyl esters. N-acyl and N-benzoyl "gangliosides" that were generated by the methanolysis w...
متن کاملSelective Synthesis of Polyoxyethylene–Polyoxypropylene Block Copolymer (Poloxamer) Fatty Acid Monoesters Over Homogeneous Organotin Catalyst
The synthesis of selected polyoxyethylene-polyoxypropylene block copolymer (poloxamer) fatty acid monoesters is presented. Organotin homogeneous catalyst Sn bis(2-ethylhexanoate) effectively catalyzed the esterification reaction of (EO)-(PO)-(EO) block copolymer (poloxamer) with fatty acids. The reaction proceeded in high yield and high selectivity to monoesters. Content of diesters in final pr...
