特徴

• Cyclodextrins (sometimes called cycloamyloses) are a family of compounds made up of sugar molecules bound together in a ring (cyclic oligosaccharides). Cyclodextrins are produced from starch by means of enzymatic conversion. They are used in food, pharmaceutical and chemical industries, as well as agriculture and environmental engineering. A cyclodextrin is the chief active compound found in Procter and Gamble's deodorizing product "Febreze" under the brand name "Clenzaire". Cyclodextrins are composed of 5 or more α-D-glucopyranoside units linked 1->4, as in amylose (a fragment of starch). The 5-membered macrocycle is not natural. Recently, the largest well-characterized cyclodextrin contains 32 1,4-anhydroglucopyranoside units, while as a poorly characterized mixture, even at least 150-membered cyclic oligosaccharides are also known. Typical cyclodextrins contain a number of glucose monomers ranging from six to eight units in a ring, creating a cone shape. thus denoting:α -cyclodextrin: six membered sugar ring moleculeβ -cyclodextrin: seven sugar ring moleculeγ -cyclodextrin: eight sugar ring molecule
