A macrocyclic (doughnut-shaped) carbohydrate ring produced enzymatically from starch. The external surface is hydrophobic while the interior is hydrophilic in nature. The hole of the doughnut is large enough to accommodate guest molecules. Uses include solubilization, separation, and stabilization of molecules in the interior cavity of or in association with the cyclodextrin molecules.
A molecule made of linked dextrose subunits that can be used in drug delivery in the body. Cyclodextrins have lipid centers surrounded by water-soluble exteriors. This combination allows fat-soluble medicines to be carried through the bloodstream to lipid-rich organs like the brain.
