Each of the six and five positional isomers of 2n- and 6n-O-alpha-D-galactopyranosyl-6(1)-O-alpha-D-glucopyranosyl-cyclomalt ohexaose (alpha-cyclodextrin, alpha CD; 2n: n = 1-6, 6n: n = 2-6), which were produced from 6-O-alpha-D-glucopyranosyl-alpha CD and melibiose by transgalactosylation with coff
