世界上最长的单词英语单词

Titin肌联蛋白是目前已知的最大的蛋白质，它的分子量为2700kDa25,000多个氨基端，长度为1μm，约占肌节的一半，是高度弹性分子。根据IUPAC国际理论和应用化学联合会命名规则，该肌联蛋白的名字足足有189819个字母，是名副其实最大的单词。 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 BookIUPAC Nomenclature of Organic Chemistry，也就是《IUPAC有机化学命名法》。

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!
