According to the Guinness Book of World Records, 18th edition, this 1,909-letter-long word is regarded as the world’s longest word in the English language. This word has also included in the American Chemical Society’s Chemical Abstracts. It is the longest real word of a Tryptophan Synthetase (its scientific name is Methionylglutaminy…serine) A protein, an enzyme that has 267 amino acids which describes a protein in the amino acid of a strand of DNA. The shortened version of this protein is known as titin, or sometimes conectin, which is involved in striated muscle formation. Its empirical formula is C132983H211861N36149O40883S693.
