Longest Chemical Name: 64,060 letters
mycro writes "A new article on Wikipedia shows the longest chemical name, reaching 64,060 letters. Methionylalanylthreonyl...leucine is a chemical name for enaptin, a nuclear envelope protein found in human myocytes and synapses, which is made up of 8,797 amino acids. It is involved in the maintenance of nuclear organization and structural integrity, tethering the cell nucleus to the cytoskeleton by interacting with the nuclear envelope and with F-actin in the cytoplasm."
Why doesn't Titin have the longest official chemical name? As a 27,000 amino acid protein, I think it has a bit of an edge.
