Abstract

The interactions of molybdate, [MoO4]2- with some uronic acids in aqueous D2O solution were studied by 1H- and 13C-NMR. Evidence is presented for a specific binding site of an Mo(VI) oxo-cation (Mo2O5(2+] with alpha-,beta-D-glucuronic acid. It is proposed that complexation involves the carboxylate oxygen (O-6b) and O-4 of the hydroxyl oxygen in a pyranose form (4C1), in the pH region 3.5-5.8.
