The story of the word

Gerardus Mulder published the name in 1838 after Jöns Jacob Berzelius suggested it in a letter, arguing that the substance was primary to life. Mulder believed all proteins were one compound with minor variations, which was wrong, but the name outlived the theory. Πρῶτος also gives protocol, originally the first sheet glued to a papyrus roll to declare what it held, and protagonist, the first competitor.
