Etymology
The term 'protein' was coined in 1838 by the Swedish chemist Jöns Jacob Berzelius. He suggested the name to the Dutch chemist Gerardus Johannes Mulder, who was studying these fundamental organic substances. The name derives from the Greek word prōteios, meaning 'primary', which itself comes from prōtos, meaning 'first'. This nomenclature reflects the early scientific understanding that proteins were the primary, most essential nitrogenous component of all living tissues, holding a position of first importance in animal and plant nutrition.
