Fucose

 

(also 6-deoxy-galactose), a monosaccharide of the de-oxyhexose class. Fucose is found in many natural compounds, in which it occurs mainly in the L-form. It is found in the L-form, for example, in certain bacterial and plant polysaccharides, in oligosaccharides in milk, and in glycoproteins including substances of blood groups. D-fucose is a component of certain plant glycosides. L-fucose has the structural formula

Enzymes known as fucosidases split the fucose radical from polysaccharide molecules.
