What is 1,6-ANHYDRO-BETA-D-GLUCOPYRANOSE?
Description
Levoglucosan, a substance formed by heating carbohydrates, has an unusual heterocyclic bicyclo[3.2.1]octane structure. In 1970, C. M. Lakshmann and H. E. Hoelscher reported that it can be produced in large quantities by?pyrolyzing cornstarch under the proper conditions. Levoglucosan is often used as a marker for detecting biomass burning in air quality studies. It is also an?initial product of wood decomposition during forest fires.

General Description
1,6-Anhydro-β-D-glucose (Levoglucosa), belonging to the class of anhydrosugars, is an indicator of the burning of biomass in atmospheric aerosol, snow, and ice. It is formed via pyrolysis of glucans, such as cellulose and starch. Levoglucosa is also found in municipal waste and thermochemical processing products of biomass and soil.
