Study Notes
Proteins
- Proteins contain approximately 16% nitrogen.
- Berzelius suggested the name "protein" because it is derived from the Greek word "proteios", meaning "of first importance", to emphasize their importance in living organisms.
- The monomers of proteins are called amino acids.
- Proteins are made up of one or more chains of amino acids, also known as polypeptide chains.
- The molecular weight of protein molecules ranges from a few thousand to over a million daltons.
