  <name>Glucosan</name>
  <description>Glucosan is a monosaccharide anhydride compound present in biomass combustion smoke, and is a tracer for biomass burning sources in atmospheric aerosol particles. A product of cellulose combustion; when cellulose is heated to over 300 degree centigrade, it undergoes various pyrolytic processes, yielding a highly combustible tar, a major constituent of which is glucosan, a dehydrated glucose containing a ketal functional group.; Glucosan is a saccharide constituent of human urine, detected with one-dimensional thin-layer chromatography, and further studied by gas chromatography-mass spectrometry. It was identified in approximately 20% of all urine samples investigated. Excretory levels varied widely from zero up to 5.3 mmol/l. (PMID: 3757263, 16448658, 16317539). Glucosan is found in sweet orange.</description>
