查询词典 key chains

It is not a single molecule, but a mixture of amylose (straight chains of glucose subunits) and amylopectin.

淀粉是葡萄糖的多聚体，不是一个单独的分子，而是直链淀粉和支链淀粉的混合物。

The glucose chains are unbranched in amylose and branched in amylopectin, which occur mixed in starches.

葡萄糖链的形式有直链淀粉和支链淀粉，混合出现于淀粉中。

Due to their superior anticorrosive capacity they will be outstanding chains lubrication in corrosive ambience, near the sea.

由于其极佳的抗蚀性能，即使在海洋与腐蚀环境中，也可提供卓越的链条润滑。

In silk, it would be better to describe the chains as being antiparallel.

在蚕丝中，更确切地讲，这些链是反向平行的。

The peak in 1673 〓 present antiparallel pleated sheet structure in the main chains.

反β片层结构是非常稳定的蛋白质组成方式，检测结果告诉我们，半乳糖导致白内障的发生是引起蛋白质组成的变化，而没有改变蛋白质基本的空间亚结构的改变。

The results of this study indicate that when these cyclic peptides self-assemble as either parallel or antiparallel stacking modes, hydrogen bonds could be formed between side chains of Asn, Asp, Gln and Glu.

结果表明，四种环状多肽无论以平行还是以反平行的方式聚集，聚集体中相邻两个环状多肽的侧链之间都能形成氢键。

By the present of DMF, attractions arising from hydroxyl groups increase, repulsions arising from apolar side-chains have little change.

混合溶剂中DMF的存在，使含-OH的极性侧链间的吸引作用增强，而对非极性侧链间的排斥作用影响不大。

Moreover, the results of IR spectrum and apolar component of surface free energy showed that the alkyl chains of OTS tilted on the surface of PTW after the modification.

但是聚合物包裹为物理包裹，与PTW表面作用力弱；而硅烷偶联剂改性虽然可以有效改善粉体疏水性，但不能满足对粉体越来越高的疏水性要求[5]。

Two amino acid molecules associate in a side-by-side manner. Interactions involving hydroxyl group and apolar alkyl groups side-chains are significant in the pairwise association of amino acids.

氨基酸两分子间的结合主要是一种肩并肩的偶极吸引作用，羟基、非极性侧基均会参与相互作用。

However,after addition a little apolar molecules,apolar molecules insert into hydrophobic microdomains,which makes PPO chains extend at certain degree,and the order of LLC increases.Therefore,the systems will supply favorable conditions for enhancing the solubility of oil-soluble molecules,which further expands application prospects of the systems.

而加入少量极性较小的油溶性分子后，油溶性分子填充到PPO链段间，使得PPO链段在一定程度上得到伸展，液晶层间距增大，两亲分子排列的有序性增强，这就为油溶性分子的增溶提供了有利条件，扩展了该体系的应用前景。

If you were not , and OS X just booted normally, have no fear.

如果你没有，和OS X刚刚启动通常，没有恐惧。

I only want to preserve our all .
