Draw a tiny section of a molecule of glycogen. Include 4 monomers. If there are any branch points in the molecule, be sure you include at least one. Some starter molecules have been pre-loaded into the drawing area to save you time. You can edit these, or use the copy/paste tool to make copies. Be sure to delete any starter molecules you don't use before you submit your final answer. HO–CH, O H REX me H OH H H₂N. HO H OH OH HN ΝΗ

Draw the expanded structure of Levothyroxine. Illustrate all ways that your molecule could form hydrogen bonds with water. Do this by drawing bent water molecules as necessary and use dashed lines (---) to show H-bonding between water and the appropriate atom in the molecule. Be sure that it is very clear which atoms on each molecule are involved in the hydrogen bonds. Keep in mind that hydrogen bonds from water can only from to the polar parts of your molecule. If your drug molecule is not capable of forming hydrogen bonds with water, fully explain why not.
