世界上
最长的英文单词
有1913个字母，实际上是一个蛋白质叫“
色氨酸合成酶
”（tryptophan
synthetase）。这个单词最早出现在上个世纪60年代的“化学摘要”杂志上，因为按照当时对蛋白序列的命名方式，是把所有氨基酸序列整个列出来作为一种对蛋白质的命名方式，但之后人们很快发现这种命名方式是没有办法应用的，之后很快更改了命名规则，但这个1913个字母的单词已经发表了，并且之后被一些辞典引用，这才有了这个世界上最长的英文单词。

这个词实际上是266个氨基酸的形容词形式（yl）的罗列，最后是“serine”，所以一共是267个氨基酸。这个词的出现体现了十九世纪德语对化学的影响，以德语的命名方式，才会出现类似“ribulosebisphosphatecarboxylaseoxygenase”这么长的词汇。

下面就是这个“魔鬼级别”的英文单词：

methionylglutaminylarginyltyrosylglutamylserylleucyl
phenylalanylalanylglutaminylleucyllysylglutamylarginyl
lysylglutamylglycylalanylphenylalanylvalylprolylphenyl

有记载最长的是1，913个字母，（当然“smiles”不算^.^）
　　是“色氨酸合成酶A蛋白质”（一种含有267种氨基酸酶）的全称----
　　一般的字典上是见不着的。
　　（你可以翻翻医学专用词汇字典^_*）
　　单词如下：
