Study Notes
Proteins Overview
- Proteins contain approximately 16% nitrogen by weight.
Origin of the Term "Proteins"
- Jons Jakob Berzelius suggested the term "proteins" for these substances because they are primary or essential components of living organisms.
Protein Composition
- Proteins are made up of amino acids, which are organic compounds.
Monomers of Proteins
- The monomers of proteins are called amino acids.
Discovery about Substances in Milk and Eggs
- GJ Mulder discovered that substances in milk and eggs, previously thought to be albumin, were actually complex nitrogen-containing compounds, which led to the coinage of the term "proteins".
