Abstract

The pH dependent lactonization of trisialic acid was examined using NMR and CE techniques. The combined studies indicate that lactonization is a dynamic, pH dependent process that occurs with preferential lactonization between the carbonyl of the central residue and the reducing end C-9 hydroxyl group.
