General description

γ-cyclodextrin (γ-CD) is a water-soluble cyclic octamer of D-glucose units linked via α(1→4) glycosidic bonds. Its ability to form several inclusion complexes with organic as well as inorganic compounds makes it a potential candidate in solid and solution state determinations.

Application

用于评估暴露于药用辅料和杀微生物剂的生殖器上皮细胞活力、完整性和炎症实验的改性剂

用于研究α-、β-和γ-环糊精与二氯钒主客体相互作用的反应物
γ-Cyclodextrin hydrate may be used to form inclusion complexes with steviol glycosides, 1-propanol, tempone and di-tert-butyl nitroxide followed by their characterization by various analytical techniques.

We study by molecular dynamics simulations the hydration of beta-cyclodextrin. Our simulations show that within these barrel-shaped molecules hydrophobicity dominates, while at the top and bottom sides of the barrel interactions with water are mostly hydrophilic in nature. These results
