the metabolism of this sugar through three main carbohydrate processing pathways and how this could influence its biological activity. Using (13)C NMR spectroscopy and enzyme assays, we showed that glucose 6-sulfonate cannot enter the pentosephosphatepathway, hence decreasing pentose and nucleotide biosyntheses. In glycolysis, glucose 6-sulfonate only provides one pyruvate per monosaccharide molecule
diastereomers of the product α-amino acid cobalt(III) complexes. However, subsequent crystallization-induced asymmetric transformations in the heterogeneous reaction mixtures led to better than 90% excess of a single diastereomer after five days, and the diastereopure product triflate salts were obtained after recrystallization. Both enantiomers of isotopically substituted (3-13C, 98%)aspartic acid were produced
