Common NameLevoglucosan
DescriptionLevoglucosan is an anhydrohexose that is the 1,6-anhydro-derivative of beta-D-glucopyranose. It is formed from the pyrolysis of carbohydrates, such as starch and cellulose. As a result, levoglucosan is often used as a chemical tracer for biomass burning in atmospheric chemistry studies, particularly with respect to airborne particulate matter. Levoglucosan in urine has been shown to be highly correlated with regional fires and as a biomarker for wood smoke exposure (PMID: 19165390 ). This is because the gas emitted by the pyrolysis of wood (biomass) contains significant amounts of levoglucosan. The hydrolysis of levoglucosan generates the fermentable sugar glucose, and therefore lignocellulosic material exhibits great potential as a renewable feedstock for the production of bioethanol. Levoglucosan can also be utilized in the synthesis of chiral polymers such as unhydrolysable glucose polymers. Levoglucosan is also produced via caramelization of sugar. Consumption of caramel or caramel-containing sweets can lead to a short-term 5X increase in urinary levels of levoglucosan (from 20 uM/mM creatinine to 100 uM/mM creatinine) (PMID: 19707249 ). Urinary levoglucosan levels increase within 2 h of caramel consumption and return to pre-exposure levels within 24 h. These data suggest that diet is a major factor in determining urinary levoglucosan levels and that recent dietary history needs to be taken into account to use levoglucosan as a marker for wood smoke exposure. Excretory levels of levoglucosan vary widely from zero up to 5.3 mmol/L (PMID: 3757263 , 16448658 , 16317539 ).
