It really isn't, though. That's not how you name peptides. In particular, it is missing conformal information. Titin has multiple bands and multiple disulfide bridges that are not expressed in this word. It is, in fact, chemically inaccurate.
I point this out because nobody has ever represented the entire molecule of titin in the "correct" way like this. It would simply be too much work, and while I suppose you could code a computer to take a PDB file and spit out a IUPAC-compliant name for it, as far as I can tell, nobody ever has. Calling something a "word" when it has never been used, never been printed, and nobody knows what it even is, seems pretty silly, especially when the trivial name (and recommended name) is only five letters long.
Aside from that, titin is not the largest molecule, and thus if we allow these type of formulaic shenanigans, it would not be the longest.
