WebNov 1, 2024 · The aim of this paper was to analyze the thermal properties of γ‐cyclodextrins with different degrees of nitration and to determine the kinetic parameters of their decomposition reactions. Cyclodextrins are a family of cyclic oligosaccharides, consisting of a macrocyclic ring of glucose subunits joined by α-1,4 glycosidic bonds. Cyclodextrins are produced from starch by enzymatic conversion. They are used in food, pharmaceutical, drug delivery, and chemical industries, as well as … See more Drug delivery Cyclodextrins are ingredients in more than 30 different approved medicines. With a hydrophobic interior and hydrophilic exterior, cyclodextrins form complexes with hydrophobic … See more Cyclodextrins are prepared by enzymatic treatment of starch. Commonly cyclodextrin glycosyltransferase (CGTase) is employed along with α- See more Cyclodextrins, as they are known today, were called "cellulosine" when first described by A. Villiers in 1891. Soon after, F. Schardinger identified the three naturally occurring … See more Typical cyclodextrins are constituted by 6-8 glucopyranoside units. These subunits are linked by 1,4 glycosidic bonds. The cyclodextrins have toroidal shapes, with the larger and the smaller openings of the toroid exposing to the solvent secondary and primary hydroxyl groups See more In supramolecular chemistry, cyclodextrins are precursors to mechanically interlocked molecular architectures, such as rotaxanes and catenanes. Illustrative, α-cyclodextrin form second-sphere coordination complex with tetrabromoaurate anion ([AuBr4]-). β-Cyclodextrin … See more Cyclodextrins are of wide interest in part because they appear nontoxic in animal studies.
