  "term": "Osones",
  "field": "Chemistry",
  "definition": "An obsolescent name for 1,2-dicarbonyl sugar derivatives (1,2-ketoaldoses) with an aldehyde group at C-1 and a ketone group at C-2. Osones are usually prepared by hydrolysis of osazones, the sugar bis(phenylhydrazones), so they are products rather than intermediates of osazone formation. Reduction of an osone gives the 2-ketose, for example D-glucosone gives D-fructose.",
