Fucose is a hexose sugar with the chemical formula C₆H₁₂O₅. It is found on N-linked glycans on the mammalian and plant cell surface.

Two structural features distinguish fucose from other six-carbon sugars present in mammals: the lack of a hydroxyl group on the carbon at the 6-position (C-6) and the L-configuration. Hydroxyl group The term hydroxyl group is used to describe the functional group -OH when it is a substituent in an organic compound. ...

In the fucose-containing glycan structures, fucosylated glycans, fucose can exists as a terminal modification or serve as an attachment point for adding other sugars ^[2].
