If I get you down to a cluster of about 30 water molecules, the boiling point is a function of the size of the water droplet.
如果对于一个由30个水分子,组成的簇,沸点是,水珠尺寸的函数。
If you looked at heteronuclear molecules and you wanted to compute the bond energy, you might start with the bond energies of the two constituents.
如果你看那些相同电子的分子,你想计算共享能,你也许会从,两个组成部分的总能量。
What happens in the intestine is that food gets broken down into constituent molecules, some of those molecules are absorbed into our bodies.
在肠道中,食物必须分解成基本的组成分子,其中一些分子才能被我们的身体吸收
And where we had left off was we were going to start one example of thinking about now where we have a heteronuclear diatomic molecules, so two different atoms in terms of forming the molecule.
我们还剩下一个,异核双原子分子的例子没讲,这里组成分子的原子,是不同的。
We have either single atoms or molecules consisting of small numbers of atoms.
单原子或者分子,由很多很小的原子组成。
Again, we're going to take the linear combination of those p atomic orbitals and make what are called pi or some more sigma molecular orbitals.
同样的,我们需要得到,原子p轨道的线性组合,然后组成我们所说的,π分子轨道或者sigma分子轨道。
We'll see why they have to separate that in a minute, but they do that these lipid bi-layers solve that problem for them and they're self-assembled structures from these molecules called phospholipids.
我们马上会讲到为什么要把它们隔离开,脂质双层膜解决了这个问题,而这些自主装结构,就是由磷脂分子组成的
All of these multiatomic moieties are nonpolar.
这些分子由多原子组成,但都是非极性的。
Now, in your book, there's an example of plasmid where I've given you the exact sequence of nucleotides that makes up the whole double stranded DNA molecule.
现在在你们书里,有个质粒样本,我将组成这个双链DNA分子的,核苷酸序列写在这里了
The IgM is really five IgG-type molecules that are linked together through disulfide bonds, such that their FC portions are all pointing in and their antibody binding portions are all pointing out.
gM是由五个IgG分子组成的,IgG分子之间通过二硫键连接,免疫球蛋白尾部的FC片段都指向内侧,而抗体的抗原结合位点都指向外侧
