Longest Word?

Had to edit a short story down by 300 words for an Oz mag today, which got me to thinking...what is the longest word in the world?

1. pneumonoultramicroscopicsilicovolcanoconiosis - a lung disease apparently.
2. antidisestablishmentarianism -opposition to the disestablishment of the Church of England
3. Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch - Welsh town
4. floccinaucinihilipilification - dunno!
5. honorificabilitudinitatibus - blame Shakespeare for this one (Love's Labours Lost)

And not sure if this is true but the chemical name for the Tryptophan Synthetase protein is...deep breath....
