Chitin is the second-most abundant organic material on earth.

几丁质是地球上第二丰富有机材料。

And these special nanostructure arrangements make chitin exoskeletons incredibly tough for their weight.

这些特殊纳米结构排列使甲壳素外骨骼相对于它们重量惊人地坚固。

Chitin is molecularly similar to the cellulose we find in plants, but it's harder and more stable.

甲壳素在分子上与我们在植物中发现纤维素相似，但它更硬、更稳定。

But insects and crustaceans build exoskeletons made from chains of modified sugars called chitin.

但是昆虫和甲壳类动物外骨骼是由被称为甲壳素修制成。

Through chemical processes, all that chitin can be turned into chitosan, which is where The Shellworks comes in.

经过化学处理后，所有几丁质转变成壳聚，这时候 The Shellworks 登场。

The outer layer of a beetle's body is made of this super stiff polymer called chitin.

甲虫身体外层是由一种叫做甲壳素超硬聚合物制成。

Fungi support their cell walls  with a starchy polymer called chitin.

真菌用一种叫做几丁质淀粉质聚合物来支撑它们细胞壁。

And chitin is also the  basis for arthropod exoskeletons.

几丁质也是节肢动物外骨骼基础。

These special nanostructure arrangements make chitin exoskeletons incredibly tough for their weight.

这些特殊纳米结构排列使几丁质外骨骼相对于它们重量来说非常坚韧。

Lobsters, crabs, scorpions and spiders are other animals with an exoskeleton made of chitin.

龙虾、螃蟹、蝎子和蜘蛛是其他具有由几丁质制成外骨骼动物。

18. And here's where chitin comes in.

这就是角素来源。

If you were to zoom into a lobster's shell on the microscopic scale you'd see chitin crystals arranged like stacks of plywood.

如果你在微观尺度上放大龙虾壳，你会看到甲壳素晶体像胶合板堆一样排列。

These are made of a naturally occurring polymer called chitin, which is a polymer you find in most insect and crustacean exoskeletons.

这些鳞片是由一种叫做甲壳素天然聚合物构成，而在大多数昆虫和甲壳类动物外骨骼中都能找到这种甲壳素聚合物。

And that's thanks in part to a substance in their cell walls called chitin.

而这某种程度上要感谢它们细胞壁中一种叫做角素物质。

By weight, chitin accounts for about 30% of the shell, and it's also the case that with lobsters, they're eaten out the restaurant.

重量上，龙虾壳30％是几丁质，但是龙虾是在餐厅里食用。

Structurally they have more in common with animals in that they build their cells from chitin, a material that gives them their distinctive texture.

从结构上说，它们与动物有着更多共同点，因为它们是几丁质构建自己细胞。那种材料使用其质地与众不同。

They jumped ship, leaving the chitin rafts  behind to be full-time photosynthetic drifters.

他们跳船，留下几丁质筏，成为全职光合作用漂流者。

Plus, they were covered from their rounded heads to their many segmented feet in an exoskeleton made of calcite and chitin.

此外，它们从圆圆脑袋到许多分段脚都被方解石和几丁质制成外骨骼所覆盖。

A piece of chocolate, you are allowed bits of insect chitin in the chocolate because they do fall in, they get everywhere.

一块巧克力， 你可以在巧克力中加入一些昆虫几丁质， 因为它们确实会掉进去，到处都是。

Believe it or not, the only other place chitin is found in abundance is in the exoskeletons of insects, crabs, and such!

信不信由你，唯一能发现丰富角素其他地方只有昆虫、螃蟹之类外骨骼中。
