Protein (German)
Where does "Protein" come from?
The German noun 'Protein' was suggested in a letter by Berzelius to Mulder[1]. It is built from the Ancient Greek word 'πρωτεῖος' meaning 'primary', which derives from 'πρῶτος' meaning 'first', combined with a suffix derived from the Latin '‑īnus'[1][2]. The root 'πρῶτος' itself traces back through Proto-Hellenic to Proto-Indo-European origins[3][4].
Open questions
- The connection of the Ancient Greek word to a broader Proto-Indo-European root is uncertain because the vowel lengths are difficult to reconcile. [3]
