Inclusion Complexes of the Cyclomalto-Oligosaccharides (Cyclodextrins)

Ultrasonic absorption studies in aqueous solutions of modified β-cyclodextrins

“…P-Cyclodextrin proved too insoluble to yield sufficient a b s o~t i o n data. Yet, P-cyclodextrin (P-CD) is the cyclodextrin of most interest because its cavity size allows for the best spatial fit for many common guest moieties such as the phenyl group and surfactant hydrocarbon tails (3,4). Its use in the food, drug, and agricultural industries as an encapsulating agent to protect sensitive molecules in hostile environments is growing rapidly and it would be of special interest to determine the fundamental processes at work when this particular cyclodextrin plays host to other molecules in solution.…”

“…[3], plotting A, values against [CD]/c should yield straight lines through the origin; AV can be obtained from the slope. Figure 6 shows this plot for the DMPCD and HPPCD systems.…”

Direct Dissolution of Cellulose: Background, Means and Applications

“…The driving force for inclusion of a hydrophobic substance in a cyc l o d e x t r i n r i n g s h o u l d b e c o n s i d e r e d a n "atypical" hydrophobic interaction, since it is not entropy driven [40]. An extensive overview of cyclodextrins as inclusion complexes was published by Clarke et al and explains many aspects of the amphiphilicity of these substances [41].…”

Percutaneous absorption enhancers: mechanisms and potential

“…These are cyclic oligosaccharides formed by at least 6 glucose units, being that the most well known are α-cyclodextrin (6 units), β-cyclodextrin (7 units) and γ-cyclodextrin (8 units), which are obtained from starch by the action of the cyclodextrine-glycosil-transferase (CGTase) enzyme (Clarke et al, 1988). The cyclodextrin ring, with an elevated number of glucose molecules, becomes very flexible, and is able to accommodate molecules in its interior.…”
