1·What drives this polypeptide chain to fold up?

是什么趋势这些多肽链折叠呢？

2·This spatial configuration of the polypeptide chain is the secondary structure.

肽链的这个空间构象就是二级结构。

3·What is the approximate molecular weight of a protein with 682 amino acid residues in a single polypeptide chain?

一含682个氨基酸残基的单个多肽链的大致分子量是多少？

4·This process continues until the polypeptide chain is complete; the chain is then released and folds into a functional protein.

这一过程持续进行直到多肽链完成；这条链然后被释放出来并折叠成有功能的蛋白质。

5·Also, the modulation of polypeptide chain and solvent environment on secondary structure of peptide segment was discussed.

并讨论了蛋白质肽链和溶剂环境对肽段二级结构的调制作用。

6·The primary structure is concerned with the number and type of amino acids present and their sequence in the polypeptide chain.

初级结构与氨基酸数量和类型，以及它们在多肽链上的排列次序有关。

7·Translation occurs at a site called the ribosome, which allows the information within the mRNA to be converted into a polypeptide chain.

翻译发生于核糖体上，在那里将mRNA的信息转变为多肽链。

8·Other amino acids such as proline and hydroxyproline (inlino group) can have a marked change in the direction of the polypeptide chain.

有一种称为脯氨酸的氨基酸实际上并不是氨基酸，而是亚氨基酸。

9·By finding these places where the nonpolar groups exist, the researchers better understand where folding occurs along a linear polypeptide chain.

通过找出非极性基团出现的位置，研究者们能更好的理解折叠沿着线形肽链发生的位置。

10·Some proteins consist of more than one polypeptide chain, and the association of these subunits in the protein gives rise to the quaternary structure.

一些蛋白质不只是由一个多肽链组成的，并且这些蛋白质亚基的结构产生了四级结构的。
