Contents of three higher fatty acid esters ( ethyl palmitate, ethyl olena-te, ethyl linoleate) during the process of rice or sorghum fermentation and distillation of Site wine were determined. 主要研究了四特酒两种原料(高粱与大米)在发酵、蒸馏过程中3种高级脂肪酸乙酯含量的变化。
The triesters of C_ ( 22)-tricarboxylic acid could be prepared by the Diels-Alder adduct using methyl ester of cottonseed oil as raw material, change non-conjugated methyl linoleate into conjugated methyl in the presence of catalyst, then react with diesters of fumarate. C22-三元酸三酯的合成以棉籽油甲酯为原料,将非共轭的亚油酸甲酯在催化剂作用下转化成共轭亚油酸甲酯,同时与富马酸二酯发生Diels-Alder反应,生成C22-三元酸三酯。
Linoleate isomerase and its properties 亚油酸异构酶及其性质
Research advance in linoleate isomerase 亚油酸异构酶研究进展
Linoleate isomerase can convert linoleic acid into conjugated linoleic acid. 亚油酸异构酶可以把亚油酸转化为共轭亚油酸。
By Sketchy Method Alternately ( SMA) rate constant of oil and fat hydrogenation reaction was calculated, and furthermore Selectivity Ratio ( SR) of linoleate and linolenate was calculated respectively in the paper. 提出迭代作图法,用以计算油脂氢化反应速率常数,进而计算三烯酸(酯)、二烯酸(酯)的选择性比(SR)。
, white floc ( induced by the change of dissolution conditions of ethyl oleate, ethyl palmitate, ethyl linoleate and fusel oil), brown yellow precipitate ( induced by iron ion), and greasy substances ( produced by aroma-producing substances in liquor). 白色絮状沉淀主要由3种高级脂肪酸乙酯,即油酸乙酯、棕榈酸乙酯、亚油酸乙酯和杂醇油的溶解条件变化而引起;棕黄色沉淀主要是由铁离子形成的棕色沉淀物质;
Studies on lipases-catalyzed oleyl linoleate synthesis in nonaqueous media 非水介质中脂肪酶催化亚油酸油醇酯合成的研究
Linoleate isomerase gene and the upstream non-coding region gene were sequenced. Contrasted to Lactobacillus P8, nucleotide mutation sites were searched in oder to validate and describe the prediction of bioinformatics. 将亚油酸异构酶基因及其上游非编码区基因进行测序,对比出发原始菌株后,寻找核苷酸突变位点,对生物信息学的预测进行验证和说明。
Qualitative analysis by gas chromatography showed that the main group of biodiesel which synthesis from waste food oil is divided into palmitic acid methyl ester, methyl oleate, methyl linoleate and methyl linen. 经气相色谱定性分析,由废餐饮油合成的生物柴油主要组分为棕桐酸甲酯、油酸甲酯、亚油酸甲酯、亚麻酸甲酯。
Ferulic acid also showed very good protection on linoleic acid and its ester, methyl linoleate against autoxidation and AAPH-induced oxidation respectively. 阿魏酸也表现出非常良好对于AAPH引发的氧化亚油酸,亚油酸甲酯的氧化的抗氧化能力。
Methyl linoleate displayed a certain capacity of transdermal absorption, but the role of penetration aid of DMSO was not obvious. 亚油酸甲酯具有一定的透皮吸收能力,但是DMSO的促皮吸收作用不明显。
