sialic acids

si·al·ic ac·ids (Sia),

(sī-al'ik as'idz),
Esters and other N- and O-acyl derivatives of neuraminic acid; radicals of sialic acids are sialoyl, if the OH of the COOH is removed, and sialosyl, if the OH comes from the anomeric carbon (C-2) of the cyclic structure; for example, N-acetylneuraminic acid.

The ubiquitous H1N1 and H3N2 flu strains, for example, use the protein hemagglutinin (H) to bind to matching sialic acid receptors on the surface of a cell before penetrating it, and then use the enzyme neuraminidase (N) to cleave or split these sialic acids when viral particles are ready to exit and spread the infection.
