The IUPAC nomenclature for organic chemical compounds is open-ended, giving rise to the 189,819-letter chemical name Methionylthreonyl threonyl . . . iso leucine for the protein also known as titin, which is involved in striated muscle formation. In nature, DNA molecules can be much bigger than protein molecules and therefore potentially be ...
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 longest recognized systematic name is for the protein titin, at 189,819 letters. [1] While lexicographers regard generic names of chemical compounds as verbal formulae rather than words, [2] for its sheer length the systematic name for titin is often included in longest-word lists.

A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
