The anomeric distributions of the furanose forms of fructose-6-P and fructose-1,6-diP have been found by 13C NMR to be 20 ± 4% α and 80 ± 10% β. The dissociation constants of the Mn complexes of fructose-1,6-diP and of a configurationally stable cis-1,6-diP analog are similar to those of various Mn-monophosphate complexes and are therefore inconsistent with chelation of the Mn by the cis-diphosphoryl moieties. Thus the affinity for metal is an unsatisfactory method for diagnosis of anomeric equilibria.
