Methionylthreonylthreonylglutaminylarginyl...isoleucine

A shortened version of the longest english word. The actual word has about 900,000 characters (189,819 to be specific). It is the chemical name for titin, which is the largest known protein. The word is obviously rarely used as it takes about 3 hours to pronounce, and it would be a lot quicker to just say "titin".

If you want some big protein, might want to look for something with a lot of Methionylthreonylthreonylglutaminylarginyl...isoleucine

Titin is the largest protein yet discovered. Its full chemical name is 189,819 letters long and, depending on how you define a “word” is the longest word in the English language. It is not included in the dictionary – few lexicographers
accept chemical formulae as words. But when people go round Googling “What’s the longest word in the English language?”, they don’t really care if it’s a “real” word or not.
