Study Notes
Protein Structure and Function
- Proteins are polymers of amino acids
- Twenty different amino acids with variable side chains (R groups)
- Amino acids linked by peptide bonds to form polypeptide chains
- Primary structure: specific linear sequence of amino acids
- Secondary structure: polypeptide chain folds into spirals (alpha-helices) or sheets (beta-pleated sheets) due to hydrogen bonds
- Tertiary structure: 3D folding of the polypeptide chain due to interactions between R groups
- Quaternary structure: multiple polypeptide chains bind together
- Proteins' functions include: structural support, transport, enzymes, antibodies
Protein Types and Functions
- Some proteins maintain shape (structural proteins)
- Others transport molecules in or out of cells (transport proteins)
- Enzymes speed up chemical reactions
- Antibodies bind to foreign substances like bacteria and target them for destruction
