Longest Word

I was just sitting here studying biochemistry and I think I have come across the longest word I have ever seen:

5-Hydroperoxyeicosatetraenoate.

I don't want to brag, but I've seen quite a few long words in my day. hehe. But come on, seriously, how do you even say this? Most words in chemistry are usually hyphenated, which really discredits them as words. But I think 5-HPETE, as it is abreviated, would count as a completely bonified word, in my opinion, due to the lack of hyphenations. This is a 28 letter word, I mean come on, if you were playing scrabble you wouldn't even be able to play this word because the scrabble board is only 15 by 15, not to mention you only have 8 or so letters to work with at a time. If you think you can beat this 28 letter word, post it below.

This just in: I checked wikipedia and found a 71 letter word:

Twoallbeefpattiesspecialsaucelettucecheesepicklesonionsonasesameseedbun. MMMmm that sounds good right now. Is there a 24 hour McDonalds in Grenada that I can get to via cab right now? Probably.

P.S. 5-HPETE is a intermediate to leukotrienes, inflamatory molecules in the body.
