Abstract
An X-ray crystallographic study has confirmed that the potassium bisulfite adducts Of D-glucose and D-mannose have open-chain structures with R and S configurations respectively at C-1. NMR studies have shown that each sugar gives rise to two bisulfite compounds, and solution-state structures and co nformations of these isomers have been deduced from analysis of H-1 NMR spe ctra. C-13 NMR data for the four adducts are given. Furanose forms of the D -glucose and D-mannose have been detected in the equilibrium solutions. (C) 2001 Elsevier Science Ltd. All rights reserved.
