    • 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.
