Suggested Study Questions:
- What does the "cyclo" part of the name in cyclodextrin refer to?
- Use the structure above to determine the molecular formula for alpha-cyclodextrin.
- Use the molecular formula to determine the empirical formula for alpha-cyclodextrin.
- Calculate the percentage composition of alpha-cyclodextrin.
- Draw the structure of alpha-cyclodextrin and locate and identify the functional groups.
- Use a diagram to explain how alpha-cyclodextrin dissolves in water.
- Use a diagram to explain how alpha-cyclodextrin could be used to remove lead ions from water.
- Draw the structure of alpha-cyclodextrin an clearly identify all 6 of the sugar molecules making up the structure.
- Activated carbon is commonly used to remove contaminants from water. What benefits do you think there might be in using cyclodextrin-derived absorbant materials instead of activated carbon?
