Note

Lactosamine is a disaccharide composed of galactose b1,4-linked to N-acetylglucosamine, and is a common constituent of complex N-linked glycans in metazoans. Unmodified terminal lactosamine, however, is less typical in tissues, since it is often further modified by additional substitutions, such as fucose, sialic acid, or sulfate to form a number of significant receptor and signaling molecules. Lactosamine-containing glycans are also required for proper targeting and maintenance of olfactory axons, and may also function in other sensory regions.(PMID: 17111357).
