字母最长的单词是什么

时间: 巩诗3757 分享

  我们从初中或者更早开始就学习了英语,那么大家知道英语字母中最长的单词是什么么?下面由学习啦小编帮大家整理资料。

  世界上最长的单词共189819个字母,读完需三个多小时

  肌联蛋白这个词在中文里只有四个字啊四个字,而它的英文学名有多少个字母?十八万九千八百一十九个!对,你没看错,就是189819个字母!这么坑爹的单词是怎么诞生的?这就要从IUPAC命名法说起了。

  这个世界上有一个名叫International Union of Pure and Applied Chemistry(国际纯粹与应用化学联合会)的组织,它最有名的工作就是定义化学等领域的专有名词。它出过一本“蓝宝书”(你没看错,它的外号就是The Blue Book)IUPAC Nomenclature of Organic Chemistry,也就是《IUPAC有机化学命名法》。

  理科狗们在高中和大学阶段一定被系统命名法折磨过吧?想想2,2,5-三甲基己烷之类的东东。这就是IUPAC命名法的中文版。如果翻译成英文,三甲基己烷的单词长达15个字母trimethylhexane。你以为这就算长单词?呵呵,请看“孟二醇”三个字的英文版:2-hydroxy-α,α,4-trimethylcyclohexanemethanol。这个单词有多长?数学不好+密集恐惧症的小编已经数不过来了。

  因此,一旦遇上某些链啊、基啊特别多的化合物,它的名称也就长的丧心病狂。骨骼肌中含有一种名叫肌联蛋白的蛋白质,它有25000多个氨基端。这直接导致它的学名成为最长的英文单词,长度为189819个字母!

  这直接导致了IUPAC的蓝宝书从未发行过纸质版本。
