Product Introduction
Due to its hydrophilic outer rim and hydrophobic cavity, cyclodextrin can serve as a host similar to an enzyme, offering a hydrophobic binding site that encapsulates various suitable guests, including organic molecules, inorganic ions, and gas molecules. Cyclodextrins have garnered significant attention and found wide applications in catalysis, separation, food, and medicine.
Apart from the characteristics and uses of other CDs, the inner cavity size of α-CD being smaller than that of β-CD makes it more suitable for accommodating small molecules and applications requiring high CD solubility.
