protein (English)
Where does "protein" come from?
The word 'protein' traces its roots back to the Ancient Greek word 'prōtos,' meaning 'first,' reflecting its essential role in biological life. This concept was developed into the term 'prōteios' and later coined by chemist Gerardus Johannes Mulder in the 1830s. The term reached English via French and German adaptations, highlighting these molecules as the primary building blocks of the natural world.
