Crystal structure of the γ-cyclodextrin n-propanol inclusion complex; Correlation of α-, β-, γ-cyclodextrin geometries

Encapsulation of ethylene gas into α-cyclodextrin and characterisation of the inclusion complexes

“…The a-CD has less symmetrical conformation in the uncomplexed form (Lindner & Saenger, 1980). Thus multiple resonances of carbons in the a-CD molecule can be seen in the NMR spectrum (Lu, Shin, Nojima, & Tonellia, 2000).…”

The structures of the isomer C of the macrobicyclic polyether (21S,26R,29S,34R)-21,22,23,24,25,26,29,30,31,32,33,34-dodecahydro-1,4,7,14,17,20,28,35-octaoxa[23,29-anti.218,34anti][7.7]orthocyclophane at 295 K and of its methanol complex at 295 and 123 K

“…For example, with Dianin's compound, 4-p-hydroxyphenyl-2,2,4-trimethylchroman, as the host, the ethanol guest is disordered and not close enough to the host to be hydrogen bonded (Flippen, Karle & Karle, 1970). In an a-cyclodextrin inclusion complex of methanol, the alcohol was found to be disordered, but some hydrogen bonding was postulated (Hingerty & Saenger, 1976), while with y-cyclodextrin the included n-propanol could not be located (Lindner & Saenger, 1980).…”

Optimization of the fermentation conditions for the mutant strain of β-cyclodextrin glycosyltransferase H167C to produce cyclodextrins

“…The main natural CDs are classified into α, β and γ CD containing 6, 7, and 8 glucopyranose units, respectively (Alves-Prado et al 2008). The structure of CD has a hydrophilic outer surface and a hydrophobic cavity (Lindner and Saenger 1980). Cyclodextrins are widely used in food, cosmetic, and pharmaceutical industries, because they have the ability to form water-soluble inclusion complex with a wild range of substances and reshape their physicochemical properties (Alves-Prado et al 2008).…”
