Levoglucosan

Levoglucosan is a simple sugar, specifically a monosaccharide, that is derived from the thermal degradation of cellulose and other polysaccharides during combustion processes, particularly in biomass burning. It is a cyclic sugar alcohol and can be regarded as a dehydration product of glucose. Chemically, levoglucosan is known for its significance in atmospheric chemistry and environmental science, as it is often used as a marker for biomass burning in the atmosphere.
