Hexakis(3-O-methyl)-i-cyclodextri n( 3i) bound to m- and p-nitrophenolate ions more strongly, whereas hexakis(2O-methyl)-i-cyclodextri n( 2i) bound less strongly than native i-cyclodextrin. ROESY spectra showed that the 3-Omethyl groups of 3i interac

A 1H NMR spectroscopic study showed that the side chains of Trp residues of chicken egg white lysozyme in an aqueous solution are included by Glucosyl-β-cyclodextrin (G1-β-CD). The 1H NMR signals due to Trp residues shifted with the addition of G1-

Circular dichroism and fluorescence spectroscopic measurements showed that the thermal denaturation and renaturation processes of bovine pancreatic ribonuclease A (RNase A) in an aqueous solution at pH 7.0 are greatly affected by the addition of gluc
