Talose is a monosaccharide with six carbon atoms. This sugar is in a group of aldohexoses with the molecular formula C6H12O6. D- Talose occurs in nature - albeit in small amounts - as part of the antibiotic effect Hygromycine (formed by streptomycetes ) ago.

As with any sugar (except dihydroxyacetone), there are two enantiomeric forms, such as image and mirror image behave.

Properties

In aqueous solution it is partly to an intramolecular ring closure so that an equilibrium between the aldehyde and the two ring forms ( furanose and pyranose ):
