Primary – of first importance
The word “protein” comes from the Greek word “prōteios,” which means “primary” or “of first importance.” This Greek root, prôtos (πρῶτος), means “first,” reflecting the essential role proteins play in biological processes. The term “protein” was coined by the Dutch chemist Gerardus Johannes Mulder in 1838, based on advice from the Swedish chemist Jöns Jacob Berzelius, who recognized the fundamental importance of proteins in living organisms.
The name reflects the idea that proteins are the building blocks of life, vital to the structure, function, and regulation of the body’s tissues and organs.
