Polysialic acids (PSAs) are polymers of N-acetylneuraminic acid. Depending on their glycosidic linkages, these sugar polymers exist in nature as a-2,8-, a-2,9-, and a-2,8/2,9-linked polysaccharides. [1] PSAs have been reported to demonstrate many important biological functions. [2] For example, a-2,

A simple and selective method has been developed to obtain both monolactones of the title compound, a model compound for biologically important polyneuraminic acid derivatives: acidic lactonization and alkaline hydrolysis of dilactone 1. The two monolactonized trimers can be separated by capillary e

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 gro
