Melezitose

Melezitose, also spelled melicitose, is a nonreducing trisaccharide sugar that is produced from lice such as Cinara pilicornis by an enzyme reaction. This is beneficial to the insects, as it reduces the stress of osmosis by reducing their own water potential. The melezitose is part of the honeydew of the honey produced by bees, and acts as an attractant for ants. This is useful to the lice as they have a symbiotic relationship with ants. Melezitose can be partially hydrolyzed to glucose and turanose the latter of which is an isomer of sucrose.
