Daunosamine is a deoxy sugar and amino sugar of the hexosamine class.

Since all these cases involves the removal of an -OH group, they are all deoxy sugars.

State the Sugar is deoxy sugar.

Deoxy sugars are sugars that have had a hydroxyl group replaced with a hydrogen atom.

The glycal double bond also allows a deoxy position (carbon in the ring that doesn't have an oxygen bonded to it) to be easily introduced.

Many studies have shown that a ribopurine rich strand bound to a deoxypyrimidine rich strand has a higher stability than the corresponding all deoxy strands which, in turn, have a higher stability than a deoxypurine rich strand bound to a ribopyrimidine rich strand [ 26 27 ] .
