In γ-cyclodextrin, the eight glucose subunits are linked end to end via α-1,4 linkages. The result has the shape of a tapered cylinder, with 8 primary alcohols on one face and 16 secondary alcohol groups on the other. The exterior surface of cyclodextrins is somewhat hydrophilic whereas the interior core is hydrophobic.
Q: What are the differences between the three basic cyclodextrins?
A: Alpha cyclodextrin, beta cyclodextrin, and gamma cyclodextrin are the three commonly used basic cyclodextrins, and their raw materials are tapioca starch or corn starch. The difference is reflected in the following two points:
First, the diameter of the cyclodextrin cavity is different;
Second, the solubility of cyclodextrin in water is different.
