1. Amino acids I 2. Peptide bond I 3. Proteins I 4. DNA I 5. Miscellaneous

3. Proteins

• macromolecules / polymers
• ' workhorses of the cell '
• made up of various L-amino acids connected by peptide bonds
• linear chains (unbranched)
  • protein molecule that consists of a single polypeptide chain is said to be monomeric
  • proteins made up of more than one polypeptide chain are called oligomeric
• interact with other proteins, nucleic acids, small molecules, ions, etc.
