The kinked configuration is called the" cis isomer" and the straight one is the trans isomer.

结状排列成“顺式体”线状排列，成“反式体”。

These different structures for compounds that have the same molecular formula are called isomers.

具有相同分子式的化合物的这些不同结体。

So the number of atoms is butane only allows for 2 isomers, n-butane and isobutane.

所以原子数是丁烷只允许2种体， 正丁烷和丁烷。

Also, ketamine itself, S-ketamine is an isomer of ketamine that's been patented for depression.

此外，氯胺酮本身，S-氯胺酮是氯胺酮的一种体，已专利用于治疗抑郁症。

But pentane, C5H12, has 3 possible isomers and C6H14, known as hexane, has 5.

但是戊烷 C5H12 有 3 种可能的体， 而己烷的 C6H14 有 5 种。

They're not structural isomers like n-butane and i-butane, instead, they're what we call cis-trans isomers.

它们不是像正丁烷和丁烷那样的体，而是我们所说的顺反体。

But if the parts are different, it's possible to have two totally different isomers of the same compound.

但如果这些部分不同，就有可能形成同一化合物的两种完全不同的体。

But they're also going to kind of lock the molecule in itself so you get formation of isomers.

但它们也会将分子本身锁定, 从而形成体。

Thus, no isomers with alkynes. Phew. OK I'm done describing for the moment.

因此，炔烃没有体。松了口气。好吧，我暂时先描述到这儿。

You would have to break the pi bond, and thus, the entire molecule to rotate between isomers.

你需要断裂π键，从而旋转体就需要破坏整个分子。

But looking at this table of the number of possible isomers you could see that that escalated quickly.

但是查看这张可能的体数量表， 您会发现它迅速增加。

Well we know that they're unsaturated alkenes because saturated fats don't have double bonds, and thus, can't have cis- and trans- isomers.

我们知道它们是不饱和烯烃， 因饱和脂肪没有双键，因此不会有顺式和反式体。

They call that isobutane and it is an isomer of butane, but according to these all important rules of nomenclature, it's not actually any sort of butane at all.

他们其丁烷， 它是丁烷的体，但根据所有重要的命名规则， 它实际上根本不是丁烷。

With the information we have, this 2-butene could be one of two different isomers: one with the methyl groups on the same side or one with the methyl groups on different sides.

根据我们掌握的信息，这个2-丁烯可能是两种不同的体之一：一种是甲基位于同一侧， 另一种是甲基位于不同侧。

Evolution has provided a goodly range of these in the form of enzymes, which are large, complicated and sometimes temperamental protein molecules, but which have the advantage that they can create pure versions of what are known as optical isomers.

进化以酶的形式提供了大量的这类物质，这些酶是大型的、复杂的、有时还会变化无常的蛋白质分子，但它们的优点是可以产生光学体的纯净版本。
