乙酰化

The acetyl-CoA carboxylase is the rate-limiting enzyme of fatty acids synthesis.

乙酰辅酶A羧化酶催化脂肪酸合成的第一步，是脂肪酸合成的限速酶。

The method controls the catalytic speed of the microencapsulation glucose oxidase through adjusting the molecular weight and the degree of deacetylation of microcapsule exine chitose, thereby the method is beneficial for oxidation-linking of gluten protein and for increasing the quality of the flour and flour products, simultaneously, the glucose oxidase after microencapsulation avoids the contact between enzyme and the flour and improves storage and the stability, and the microencapsulation glucose oxidase is excellent flour modifying agent and accords with practical production and application.

该方法通过调节微胶囊外壁壳聚糖的分子量和脱乙酰度，控制微胶囊内葡萄糖的催化速度，从而有利于面筋蛋白的氧化交联，提高面粉及其制品的品质；同时葡萄糖氧化酶经微胶囊化以后避免了酶与面粉的接触改善了贮藏和稳定性，是优良的面粉改良剂，符合实际生产应用。

To evaluate the effect of deacetylation degree on the gelation behavior of thermosensitive chitosan-β glycerol phosphate disodium salt pentahydrate system and to compare their rheological behaviors before and after gelation.

目的 研究壳聚糖（chitosan，CH）脱乙酰度（degree of deacetylation，DDA）对CH-甘油磷酸盐温控体系凝胶化行为的影响，同时比较其在凝胶形成前后的流变学行为差异。

Hepatic sinusoid capillarization plays an important role in occurrence of portal hypertension. The fenestra of endothelial cells in hepatic sinusoid reduces and the diameter of fenestra decreases. The formation of basement membrane impaires the substance exchange between blood and hepatic cells,which results in oxygen deficiency, metabolic product accumulation and cell necrosis.

肝窦毛细血管化在硫代乙酰胺诱导的肝硬化门脉高压发生中起重要作用，肝窦内皮细胞窗孔减少并减小，内皮细胞下基底膜形成使肝细胞与外界物质交换减少，导致细胞缺氧、代谢产物聚集，肝细胞坏死，最终导致门脉高压的发生。

Methods:The target compounds were synthesized from acylation of polyethylene glycol to hydroxy group of ursolic acid by polymer polycondensation method.

通过高分子缩合的方法，将酰化的聚乙二醇接枝到熊果酸的羟基上，得到目标产物。

It was detected by DSC that the temperature of imide and crosslinking reaction are differentiated by the catalysis of acetyl acetone copper and rare earth.

DSC研究表明乙酰丙酮铜催化剂和稀土催化剂可以分开低聚物的亚胺化和交联反应温度。

OBJECTIVE: To evaluate the effect of N-Mucisol on the treatment of acute pulmonary injury and pulmonary interstitial fibrosis.

目的 ：评价N -乙酰半胱氨酸治疗急性肺损伤和肺间质纤维化的作用。

With the occurrence of H2/Pd-C and ethyl formic ester,the reduction of the nitro group and the formylation of the amino group could be finished in one step.

但是在甲酸乙酯存在下，用H2/Pd-C对Ⅶ的硝基进行还原，得到的Ⅷ中的氨基可当即被甲酰化，使由Ⅶ到Ⅳ的两步反应一步完成。

With brain stereotaxis technique PP2A was inhibited in the nucleus basalis of Meynert and the cytoskeletal protein tau, neurofilament were found hyperphosphorylated and aggregating. The neurite became short and thickening, acetyltransferase aggregated in the body of neuron and the acetylcholine level in the nucleus basalis of Meynert was significantly decreased followed with spatial memory defict of rats.

利用立体定位技术抑制大鼠基底核PP2A活性，使基底核神经元微管相关蛋白tau及神经细丝出现过度磷酸化和聚积，轴突变短增粗，胆碱乙酰转移酶在胞体聚集，而使基底核乙酰胆碱含量降低，大鼠出现空间记忆障碍。

Methods 42 Wistar male rats of hepatic fibrosis were induced by TAA and divided into 7 groups randomly (n=6). The rats of 1 model group were sacrificed every 2 weeks.

60只雄性 Wistar大鼠应用硫代乙酰胺饮用水喂养，制备肝纤维化模型。42只大鼠模型制备成功后，随机分为 7 组，每组6只。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
