查询词典 amino acids

Pyridoxine, pyridoxal , pyridoxamine as well as their phosphated forms are structural analogues in which pyridoxal-5"-phosphate and pyridoxamine-5"- phosphate are the biological active forms in vivo which act as the cofactors of aminotransferases, amino acid decarboxylases, cysteine desufbrase and cystathionine , etc by constant transconversions.

Cheese in storage for the relationships between physicochemistry, rheology andmicrostructure Reasearching for physicochemistry, microstructure and rheology of cheeses showed: as aresult of the casein hydrolysis and broken casein gel network structure, there decomposed smallermaterial. Moreover, hydrophobic amino acid residue on protein surface increased, hydrophobicinteraction enhanced, which lead to a closer connection with casein micelles.

干酪在贮藏期理化、流变学和微观结构三者的关系通过对干酪的理化、流变学和微观结构的研究表明：在干酪的贮藏过程中，由于酪蛋白的水解，酪蛋白原有凝胶网络结构被破坏，分解产生更小的物质；并且，蛋白质表面疏水氨基酸残基增多，疏水相互作用增强，致使酪蛋白结合更紧密。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
