Cyclodextrins (CDs) are compounds formed from five or more units of glucose linked by α-1,4 glycosidic bonds. The most common CDs have six (α-CD), seven (β-CD) and eight (γ-CD) glucose units forming the cone shaped structure, that is able to accommodate hydrophobic molecules within is interior, the diameter of which is approximately 5.2 A° (α-CD), 6.6 A° (β-CD), and 8.4 A° (γ-CD) . Externally, the structure is sufficiently hydrophilic to make CDs water soluble. These cyclic glucose polymers are used in the pharmaceutical, cosmetic and food industries.
