Branched cyclodextrins and method for producing them
摘要
Disclosed are novel branched cyclodextrins having any of an N-acetylglucosaminyl group, a glucosaminyl group, an N-acetylgalactosaminyl group and a galactosaminyl group bonded to the hydroxyl group of the cyclodextrin ring by beta -bonding therebetween, and their salts. The novel branched cyclodextrins are produced by reacting a solution containing a cyclodextrin and an N-acetylglucosamine or N-acetylgalactosamine with an N-acetylhexosaminidase, and optionally deacetylating the resulting product.
