Methionylthreonylthreonylglutaminylarginyl...isoleucine 

The longest known word in English, at 189,819 letters, is the chemical name of titin. Titin is the largest known protein. This word takes roughly 3 hours to pronounce.

I can't use the full chemical name of titin because it goes over the word limit. So heres a shortened form:
I just learned today that Methionylthreonylthreonylglutaminylarginyl...isoleucine is the chemical name of the largest known protein to mankind.

Methionylthreonylthreonylglutaminylarginyl...isoleucine 

A shortened version of the longest english word. The actual word has about 900,000 characters (189,819 to be specific). It is the chemical name for titin, which is the largest known protein. The word is obviously rarely used as it takes about 3 hours to pronounce, and it would be a lot quicker to just say "titin".

If you want some big protein, might want to look for something with a lot of Methionylthreonylthreonylglutaminylarginyl...isoleucine

Methionylthreonylthreonylglutaminylarginyl...isoleucine 

a very fucking long word
you can read the whole thing, just search up "copy and paste every word in existence" to find the article

Titin is the largest protein yet discovered. Its full chemical name is 189,819 letters long and, depending on how you define a “word” is the longest word in the English language. It is not included in the dictionary – few lexicographers
accept chemical formulae as words. But when people go round Googling “What’s the longest word in the English language?”, they don’t really care if it’s a “real” word or not.

guy1 i just heard about this new 189,819 letter long word, wow
guy2 what is it???
guy1 Methionylthreonylthreonylglutaminylarginyl...isoleucine
guy2 whats the "..."
guy1 its all the other 189,767 letters
guy2 wow

Titin is the largest known protein in nature, playing a crucial role in muscle contraction and elasticity. It is a structural protein found in the sarcomeres of striated muscles, such as skeletal and cardiac muscle, where it helps maintain the integrity of the muscle fiber structure and assists in the passive elasticity of muscles during contraction and stretching.

Titin's full name, often cited as the longest word in the English language, is a chemical name that describes the protein's intricate molecular structure. Its full name is 189,819 letters long and represents the precise sequence of amino acids that make up the protein. Due to the extreme length of the name, it is typically abbreviated to "titin" for practical use.

This incredibly lengthy name is a systematic description based on the protein's chemical composition, specifically the sequence of its constituent amino acids, and was coined by scientific conventions for naming proteins in a highly detailed manner. However, because the name is so long, it is not typically used in everyday scientific contexts. Instead, "titin" is used to refer to this massive protein.

Titin ( also known as Methionylthreonylthreonylglutaminylarginyl… isoleucine) , is the largest known protein, plays a vital role in the contraction of the muscles and its elasticity by connecting the Z-line to the M-line in muscle fibers.
