油酸酶

The optimal conditions of cetyl trimethyl ammonium bromidereverse micellar system,and the most suitable reaction conditions of synthesis of ethyl oleate by Lipex lipase were determined.

研究了CTAB逆胶束体系的适宜构建条件以及Lipex脂肪酶催化合成油酸乙酯的适宜反应条件。

In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid, which is transported to the bundle sheath cells, where the carbon dioxide is released, then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3-phosphate, the first step in the Calvin cycle.

在叶肉细胞的叶绿体中二氧化碳与磷酸烯醇丙酮酸结合形成草酰乙酸，后被运到邻近的维管束鞘细胞，在那里二氧化碳被释放，后被核酮糖二磷酸羧化酶固定形成3－磷酸甘油酸，这是卡尔文的循环第一步。

Adopt poaching and alcohol sinking to get coarse polysaccharide, then take MCP, MCP-1 and MCP-2 for studing in antioxidation activities. They have strong ability for scavenging free radical only in DPPH system and oxidation system of linolic acid induced by alkane radical, but negatively in hydroxyl system and in super-oxygen anions system. And MCP-2 is better than MCP-1, so we choose enzymolysis method to remove protein.

采用水煮醇沉工艺提取粗多糖，然后对MCP、MCP-1和MCP-2进行抗氧化活性试验，三者在DPPH体系和烷基自由基引发的亚油酸氧化体系中具有明显的清除自由基能力，在羟基自由基体系和超氧阴离子自由基体系中则呈现负清除能力，其中MCP-2要优于MCP-1，因此选用酶解法除蛋白。

Esterification of sorbitan and oleic acid can be carried out by lipase CAL in nonaqueous phase under mild conditions.

失水山梨醇单油酸酯作为一种重要的非离子表面活性剂，可利用脂肪酶在非水相中合成[1] 。

Results The respiration dysfunction caused by oil acid could be prominently improved by ulinastain. There was only a little expression of hemeoxygenase-1 in the lung of Group A, but the expression increased in Group B and significatively increased in Group C.

结果：乌司他丁能显著改善油酸所致急性肺损伤所致的呼吸窘迫；肺组织血红素氧化酶－1在对照组仅有少量表达，急性肺损伤组表达增多，乌司他丁干预组表达明显增强。

To develop an iphRNA vector for seed-specffic expression targeting the fad2 gene in Brassica napus L., an inverted repeated unit of the 537bp segment of the fad2 gene was first cloned into a medium vector, the pllurrican Vector, with a spliceable fad2 intron sequence in between.

通过PCR扩增分离到甘蓝型油菜种子特异性表达的NaPin启动子序列(11147bp)以及油酸脱饱和酶基因(fad2)的一个537bp的片段，并将它们分别克隆到pGEM-T easy载体中。

Lipase is completely retained by the membrane with the retention percentages of olive oil and oleic acid are 91% and 82%, respectively.

实验表明橄榄油和油酸的截留率分别为91%和82%，包衣酶全部截留在管束内。

Isooctane reversed micelles. The stability of lipase in reversed micelles was increased when oleic acid was added.

产物油酸对AOT／异辛烷反胶团中脂酶稳定性有保护作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
