... correlate with the binding affinity between GA and the receptor. The thermodynamic parameters obtained are in the range of those of other interactions with c-CD [15]. The interaction of GA with c-CD ... by the addition of c-CD. Presumably because the small pockets of a-CD and b-CD are not able to form stable complexes with GA, the binding of a-CD to GA is not observed and t...
