Rhamnose

Rhamnose is a naturally occurring deoxyhexose sugar. The most common natural form is the L-enantiomer, referred to as L-rhamnose; the D-enantiomer is rare.

In nature, rhamnose occurs widely in plants, bacteria, and fungi. It is a constituent of plant cell

Biosynthesis of rhamnose involves nucleotide-sugar pathways. In bacteria, dTDP-L-rhamnose is produced via a four-enzyme pathway from

Properties and uses: Rhamnose is a water-soluble hexose and a reducing sugar when in free form. It
