反丁烯二酸

It is broken down via phenylalanine to give acetyl CoA and fumaric acid.

它通过苯丙氨酸降解出乙酰辅酶 A 和反丁烯二酸。

Sucrose, Glucose Syrup, Pectin, Colors (berry juice, black carrot, annatto), Natural Flavors, Lactic Acid, Citric Acid and Fumaric Acid.

蔗糖， 葡萄糖，果胶(存在于如苹果、杏和葡萄等成熟的水果中)，颜色(来自浆果汁，胡萝卜，胭脂树橙)，天然口味，乳酸，柠檬酸，反丁烯二酸。

Di-methyl fumarate is an effective preservative containing such group, but it is banned to used in food because of its skin allergy.

反丁烯二酸二甲酯即为一种含有该功能团的广谱、高效、低毒的防腐剂，但由于其致皮肤过敏性在食品工业中得不到广泛的应用。

The results showed in the seven food preservative s,that calcium propionate had no effect on the growth of Peronophythoral litchii,while cinnamyl glyceroyl fumarate was the best.

结果表明：在所用的7种食品防腐剂中，丙酸钙对荔枝霜疫霉菌的生长无抑制作用，反丁烯二酸桂醇甘醇酯的抑菌效果最好

Mono-cinnamyl maleate was prepared by esterification of maleic anhydride and cinnamyl alcohol of 1 mol:2 mol at 95 ℃ for 2～4 h.Then added isomeric catalyst and mono-cinnamyl fumarate was made by reacting at 90 ℃ for 4 h.After methanol (methanol:mono-cinnamyl fumarate = 6 mol:1 mol) was added,the mixture maintained at 90 ℃ for 4.0 h to synthesize CMF.

合成试验表明：以摩尔比为1：2的马来酸酐与肉桂醇在95 ℃醇解反应2～4 h后加入异构化催化剂，90 ℃转型反应4 h后，添加6倍摩尔质量的甲醇，在90 ℃恒温反应4 h，反丁烯二酸桂醇甲酯的合成产率较高。

For pre-selection of iron compounds that ferrous sulfate, ferrous chloride, ferrous fumarate, carbonyl iron, amino acid chelated iron, iron asporotate, fenic chloride and ferric pyrophosphate were added in reconstituted skim milk to undergo in vitro digestion, respectively, and then the selected iron compounds were added in reconstituted whole milk to compare the iron bioavailability by estimating dialyzable ferrous iron, dialyzable total iron, nondialyzable and total ferrous iron, respectively.

取硫酸亚铁、反丁烯二酸亚铁、氯化亚铁、艰基铁、Iron asporotate、Amino acid chelated iron、氯化铁与焦磷酸铁等不同铁剂添加於脱脂还原乳中进行体外消化试验，並筛选生物利用性佳之铁剂分别添加於全脂还原乳中，以可透析二价铁、可透析总铁、未透析二价铁及总二价铁等作为评估之指標。

There are several methods of industrial production of fumaric acid.

工业上有多种方法生产反丁烯二酸。

The quantity of fumaric acid in Sukebing oral liquid was analyzed with the method of thin layer scan.

采用薄层扫描法对速克痛口服液中反丁烯二酸进行定量分析，平均回收率 96 。

Such polymers shall contain grafted fumaric acid at levels not to exceed 2 percent by weight of the finished polymer.

No。 26877 81 6。此类聚合物包含的接枝反丁烯二酸量

In this experiment we use the alcohol to replace the Fumaric acid and using the NaOH and HCl to control the pH number.

而本实验就是以过锰酸钾加入酒精以代替过去使用的反丁烯二酸并以HCl及NaOH来调控其酸碱值并比较其反应后的各种性质。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
