A large chained molecule will obviously have a huge name. I've seen chemical formulas in regulatory databases that were well over 250 characters long.

THREONYLSERYLPROLYLSERYLGLUTAMINYL...

That's just the formal name of a polypeptide. Any protein will have a name like that (which nobody uses anyway), so there are many thousands to choose from. AFAIK the largest known protein is titin, which has >28,000 amino acids, so it would be written as 28,000 ____yl's in a row. :Q
