Macromoleculas

Large Molecules Problem Set

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.

Instructions: The following problems have multiple choice answers. Correct answers are reinforced with a brief explanation. Incorrect answers are linked to tutorials to help solve the problem.

Recognition of the peptide bond

Identification of biological molecules

Tertiary structure of a protein

Identification of another biological molecule

Elements of protein structure

Identification of a monomer unit of a biological macromolecule

Weak forces involved in interactions between macromolecules

Identification of a macromolecule

Identification of a hydrophobic amino acid

Protein-protein interactions

Sequence of a polypeptide

Sequence of a longer polypeptide
