Sialic acid

Sialic acid is a derivative of a nine-carbon [[monosaccharide, named from the Greek σιαλοσ (sialos) 'saliva'. It is the negative charge of this chemical that is responsible for the slippery feel of saliva and mucins coating the body’s organs. Despite its role of acting as "decoy" for invading pathogens, sialic acid is becoming known as an agent necessary for mediating ganglioside distribution and structures in the brain. Sialic acid is involved in both preventing infections (mucus associated with mucous membranes--mouth, nose, GI, respiratory tract), but it also acts as a receptor for influenza viruses to allow attachment to mucous cells (an early step in contracting the flu).
