Based on our intensive studies on the lactonization of oligo/polysialic acids, we proposed for the first time that the lactone-ring formation of oligo/polysialic acids has three stages. We also provided a novel model to explain the conformational changes of oligo/polysialic acids caused by the repulsing forces among the carboxyl groups of sialic acid residues. Our results should provide novel approaches for further investigation of the structural-functional relationships of oligo/polysialic acids.
