How do proteins catalyze biological reactions? How does the structure of DNA help explain the mechanism for encoding genetic information? How is energy stored in organisms as polysaccharides and lipids? The science of structural biology provides the answers to these questions. To begin a study of structural biology, we will first learn about common biological molecules. Our objectives are to become familiar with structures and properties of sugars, lipids, amino acids, and nucleotides. We will also consider the macromolecules that are formed from these monomer units, including proteins, nucleic acids and polysaccharides.
