| Abstract: | The results obtained from a phosphorus NMR study of the interactions of Mg2+ with thiamine diphosphate confirm the existence of a Mg-thiamine diphosphate complex with a stoichiometry in which the α phosphorus seems to be the most influenced by the interaction. The variations of δ and Jαβ with various concentrations of Mg2+ are described. |
