Kang Ko OH: Wed., 11am-11:50am at CLICS 2 nd floor giko@ucsd.edu I. The following picture depicts a large protein molecule. 1. Can you identify the level of protein structure for this molecule? If so, identify it and briefly address some of the characteristics that support your answer. If not, briefly explain why. Depiction of alpha-helix and beta-sheet structures shows that this is at least a secondary structure. Also, we can see that these helices and sheets are “folded” into 3D, due to forces from the disulfide bridge, hydrogen bonding, van der Waals interaction, etc. Therefore, this molecule is a tertiary structure . 2. Is this a macromolecule? Briefly explain why. If you cannot tell from the given information, briefly explain why. Yes, this molecule is a macromolecule because it is a protein molecule. Proteins, carbohydrates, and nucleic acids are macromolecules. 3. Suppose this molecule functions as an enzyme. What is the advantage of this being a ‘big molecule’? Being large, this enzyme has larger surface area and variety of surface structures.
