Chapter 5 - Coggle Diagram

- - - - Quaternary structure results when two or more
        polypeptide chains form one macromolecule
      - Collagen is a fibrous protein consisting of three
        polypeptides coiled like a rope
      - Hemoglobin is a globular protein consisting of
        four polypeptides: two α and two β subunits
    - - Tertiary structure, the overall shape of a
        polypeptide
      - hydrophobic interactions, and
        van der Waals interactions
      - Strong covalent bonds called disulfide bridges
        may reinforce the protein’s structure
    - - The coils and folds of secondary structure result
        from hydrogen bonds
      - Typical secondary structures are a coil called an
        α helix
    - - The primary structure of a protein is its sequence
        of amino acids
      - Primary structure is determined by inherited genetic
        information
      - Primary structure is like the order of letters in a long
        word
