In its complete form, the chemical name contains 1185 letters, and is one of the longest words in English. The letter combination yl appears in the word 166 times. The term was published in the American Chemical Society's Chemical Abstracts in 1972, and is considered by some to be the longest real word. It does hold the record for the longest word published in an English language publication in a serious context - that is, for some reason other than to publish a very long word - but there are bigger proteins which would generate larger words if written. This was copied from http://en.wikipedia.org/wiki/Acetylseryltyrosylseryliso...serine.
