The longest known word in
English, at 189,819 letters, is the
chemical name of titin. Titin is the largest known protein. This word takes roughly 3 hours to
pronounce.
I can't use the full
chemical name of titin because it goes over
the word limit. So heres a shortened form:
I just learned today that Methionylthreonylthreonylglutaminylarginyl...isoleucine is the
chemical name of the largest known protein to mankind.
