Advance in structure,embedment forming ability of large cyclodextrins
Large cyclodextrins are cyclic malto-glucans with a degree of polymerisation higher than nine.Compared with the commom cyclodextrins of α-CD,β-CD and γ-CD,large cyclodextrins have new structural features and property due to their larger cavities.This review summarises the studies of the large cyclodextrins from two aspects of structure and embedment forming ability.
