Deoxy sugar
Deoxy sugars are sugars that have had a hydroxyl group replaced with a hydrogen atom. Examples include: Deoxyribose, or 2-deoxy-D-ribose, a constituent of DNA Fucose, or 6-deoxy-L-galactose, main component of fucoidan of brown algae, and present in N-linked glycans Fuculose, or 6-deoxy-L-tagatose, one of the important components of avian influenza virus particles Rhamnose, or 6-deoxy-L-mannose, present in plant glycosides In Escherichia coli bacteria, deoxyribose sugars are synthesized via two different pathways - one pathway involves aldol condensation, whereas the other pathway is conversion of a ribose sugar into a deoxyribose sugar by means of changes on the nucleotide or nucleoside level.
