Common Name

N-Acetyl-a-neuraminic acid

Description

N-Acetyl-alpha-neuraminate is a sialic acid. Sialic acids are an important family of related 9-carbon sugars acids, present on the surface of many different cells and functioning in a wide range of different biological processes. They mediate a variety of cell-cell and cell-molecule interactions in eukaryotes and can be utilized by pathogens to evade the host immune response. N-acetylneuraminic acid is the most common sialic acid, and the predominant form present in humans. It can be found as a terminal sugar on a wide range of surface glycoconjugates. A number of bacteria that can colonize humans (such as E. coli) make use of N-acetylneuraminic acid as a nutrient source.
