Ca(2+)-complexation of D-glucose and D-sorbitol have been investigated with the aid of multinuclear ((1)H, (13)C and (43)ca) NMR spectroscopy
and ab initio quantum chemical calculations. Formation constants of the
forming 1:1 complexes have been estimated from one-dimensional (13)C NMR
spectra obtained at constant ionic strength (1 M NaCl). Binding sites
were identified from 2D (1)H-(43)Ca NMR spectra. 2D NMR measurements and
ab initio calculations indicated that Ca(2+) ions were bound in a
tridentate manner via the glycosidic OH, the ethereal oxygen in the ring
and the OH on the terminal carbon for the alpha- and beta-anomers of
glucose and for sorbitol simultaneous binding of four hydroxide moieties
(C1, C2, C4 and C6) was suggested. (C) 2010 Elsevier B.V. All rights
