Levoglucosan
Levoglucosan (also known as 1,6-Anhydro-beta-glucopyranose) is an anhydrosugar, specifically the 1,6-anhydrosugar form of glucose. It is formed during the pyrolysis of glucose-containing carbohydrates such as cellulose. Some pyrolysis technologies specifically target the production of levoglucosan in high yields.
In recent years there has been significant research on developing uses and conversion pathways for levoglucosan. For example, sorbitol has been synthesised from this anhydrosugar whilst microorganisms capable of directly fermenting levoglucosan (without requiring hydrolysis to glucose) have been tested.
