Sialylated oligosaccharides are important components of glycoproteins and glycolipids and also occur as free oligosaccharides in several body fluids. In human milk, both free and bound sialylated oligosaccharides have potential biological activity and are known to inhibit viral infection. Sialyl Lewis a is increasingly expressed in melanoma cells, and hypothetically immunotherapy eliciting a humoral response could be therapeutically effective against tumors.
