Titin is the third most abundant protein in muscle (after myosin and actin), and an adult human contains approximately 0.5 kg of titin. [13] With its length of ~27,000 to ~35,000 amino acids (depending on the splice isoform ), titin is the largest known protein . [ 14 ]
As a technical scientific term, the full name of titin doesn’t appear in any dictionary—not just because it would take 12 full pages to wrangle the 190,000-odd characters, but because of the ...
The IUPAC name for Titin. This is the largest known protein and so has the longest chemical name. Written in full, it contains 189,819 letters. [48] Periplanone B: Periplanone B A pheromone of the female American cockroach. Thebacon: Thebacon Dihydrocodeinone enol acetate, an opioid analgesic or antitussive. [citation needed]
The 58-letter name Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch is the name of a town on Anglesey, an island of Wales. In terms of the traditional Welsh alphabet, the name is only 51 letters long, as certain digraphs in Welsh are considered as single letters, for instance ll, ng and ch. It is generally ...
Inserting the "full word" into this article perpetuates the myth that it is the world's longest word and the misconception that proteins are called by their amino acid names. The amino acid sequence of titin differs between species. Furthermore within humans there are several splice variants.
No legitimate biologist would consider the full name of titin even remotely useful. That said, let's imagine that laypeople comprise 100% of the titin article's readership. Let's say that all of them are here because they've heard that the full name of titin is the longest word in English. Does that mean this article should contain the word?
As in many languages, chemical nomenclature may be used to construct indefinitely long chemical names (if referring to fictional molecules), and therefore is not on this list. The chemical name of titin could be translated, and therefore would be the longest technical word in the French language.
The giant protein titin (connectin) extends from the Z-line of the sarcomere, where it binds to the thick filament (myosin) system, to the M-band, where it is thought to interact with the thick filaments. Titin (and its splice isoforms) is the biggest single highly elasticated protein found in nature.
