Daunosamine is a
deoxy sugar and
amino sugar
In organic chemistry, an amino sugar (or more technically a 2-amino-2-deoxysugar) is a sugar molecule in which a hydroxyl group has been replaced with an amine group. More than 60 amino sugars are known, with one of the most abundant being ''N'' ...
of the
hexosamine
Hexosamines are amino sugars created by adding an amine group to a hexose.
Examples include:
* Fructosamine (based upon fructose)
* Galactosamine (based upon galactose)
* Glucosamine (based upon glucose)
* Mannosamine (based upon mannose

class.
Daunosamine is a component of the
anthracycline class of
antineoplastics, linked to a derivative of
naphthacene
Tetracene, also called naphthacene, is a polycyclic aromatic hydrocarbon. It has the appearance of a pale orange powder. Tetracene is the four-ringed member of the series of acenes.
Tetracene is a molecular organic semiconductor, used in organic ...
. It is a component of birch juice.
The compound is soluble in water and responds with polymers like cellulose and lignin if it is in excess, so collection of birch juice is very helpful for the birch tree.
The dnrQ gene is required for the synthesis of daunosamine.
