Peptides are short oligomer and polymer substances made up of two or more amino acids linked in a chain.
肽是短的寡聚物或两个及以上氨基酸连接成的肽链组成的聚合体。Peptide did not break by SDS-PAGE analysis, the secondary and tertiary structure changed by infrared and fluorescence spectra analysis.
SDS-PAGE电泳分析显示处理后酶蛋白的肽链不发生断裂，但红外光谱和荧光光谱分析显示酶蛋白的二级和三级结构均发生变化。Such a huge amount of types is due to the different sequences of amino acids which compose the proteins in the peptide chains.
种参与蛋白质组成的氨基酸在肽链中的排列顺序不同所引起的。The next two stages show folds that occur between points that are farther from each other along the polypeptide chain.
接下来的两个阶段表明在沿着肽链较远的点之间的地方发生折叠。Any of a large group of enzymes that catalyze the hydrolysis of peptide bonds In the Interior of a polypeptide chaIn or proteIn molecule.
肽链内切酶在多肽链或蛋白分子内部加速肽键水解的任何较大的酶群Like light meromyosin , tropomyosin contains two peptide chains in a coiled coil conformation .
象轻酶解肌球蛋白一样，原肌球蛋白含有两个肽链，其构型为盘旋螺旋。In this paper the recognition of amino acids, saccharides, peptides, proteins and chiral drugs by calixarenes is reviewed.
本文就杯芳烃对氨基酸、糖、肽链、蛋白质等生物活性分子及手性药物的分子识别作一综述。Other amino acids such as proline and hydroxyproline (inlino group) can have a marked change in the direction of the polypeptide chain.
另一类氨基酸，像脯氨酸和羟脯氨酸，可能使肽链的方向发生明显的变化。All proteins are high molecular weight heteropolymers of amino acids joined by peptide bonds, ranging from 104 to over 106.
所有的蛋白质都是由肽链连接的氨基酸构成的高分子杂聚物，分子量大约为104到大于106之间。
