WebDec 14, 2024 · Cyclodextrin glucosyltransferase (CGTase; EC2.4.1.19), a member of the α-amylase family, is an important enzyme that catalyzes the biotransformation of starch and related carbohydrates to cyclic-oligosaccharides, called cyclodextrins (CDs) through glycosyltransferase reaction (Terada et al. 1997; Li et al. 2007 ). WebReversed-phase chromatography columns have been used for the analysis of cresols with limited success. A reversed-phase support has been developed that allows complete separation of the three cresol isomers (Bassler and Hartwick 1989).

Cyclodextrins are able to form water-soluble inclusion complexes with many lipophilic poorly soluble compounds. WebCyclodextrins (CDs) are cyclic oligosaccharides composed of six or more α-1,4-linked glucose units. CDs of 6, 7, and 8 α-d -glucose residues are called α-, β-, and γ-CD, respectively. CDs possess a hydrophilic exterior and a hydrophobic interior. new life church in canton ga
