Study Notes
Protein Structure
- Quaternary structure is characterized by the specific 3D arrangement of multiple protein subunits.
Protein Folding
- Hydrogen bonding, ionic interactions, and disulfide bonds are the bonding interactions that contribute to the stability of a protein's tertiary structure.
Protein Conformation
- A nascent polypeptide chain, or a newly synthesized protein chain, is described as a protein that has not yet achieved its functional 3D conformation.
