Primary – Of first importance
The word “protein” comes from the Greek word “proteios,” meaning “primary” or “of first importance,” which is derived from “protos,” meaning “first.” The term was coined in 1838 by the Dutch chemist Gerardus Johannes Mulder and later adopted by the Swedish chemist Jöns Jakob Berzelius. The name reflects the fundamental role proteins play in living organisms, serving as essential building blocks for cells, tissues, and various biological functions.
