摘要

Sialic acids (N-acetylneuraminic acid, NeuAc) are nine- carbon ketoses which have the unusual feature of a highly acidic carboxyl group (PK_a?2.8) immediately adjacent to the anomeric carbon. Sialic acids are typi- cally found in terminal glycosidic linkages of cell surface glycoproteins and glycolipids and are represented in species as diverse as bacteria, trypanosomes, and higher members of the animal kingdom, including humans.
