esophagogastroduodenoscopy

I thought at first it was a typo on the hospital admissions report. Try saying it ten times fast - esophagogastroduodenoscopy, esophagogastroduodenoscopy, esophagogastroduodenoscopy.... It's a diagnostic endoscopy to visualize the gastrointestinal tract up to the duondenum.

That got me to thinking about long words.

apparently, esophagogastroduodenoscopy isn't as long as

which at 1185 letters, is a coat protein of the tobacco mosaic virus.
Although the word does seem to be cheating a bit, doesn't it, since it's just spelling out the functional groups of the protein. I'm not going to try to pronounce that one.
