Study Notes
Weak Interactions in Macromolecules
- The hydrophobic effect in macromolecules is caused by the van der Waals interaction, a type of weak interaction.
Protein Structure
- The tertiary structure of a protein is characterized by the overall 3D shape of the polypeptide chain.
Bohr Effect
- The Bohr effect in hemoglobin is caused by the interactions of carbon dioxide (CO2) molecules.
