Metabolite Identification
Common NameRhamnose
DescriptionRhamnose (Rham) is a naturally occurring deoxy sugar. It can be classified as either a methyl-pentose or a 6-deoxy-hexose. Rhamnose occurs in nature in its L-form as L-rhamnose (6-deoxy-L-mannose). This is unusual, since most of the naturally occurring sugars are in D-form. Rhamnose is commonly bound to other sugars in nature. It is a common glycone component of glycosides from many plants. Rhamnose is also a component of the outer cell membrane of certain bacteria. L-rhamnose is metabolized to L-Lactaldehyde, which is a branching point in the metabolic pathway of L-fucose and L-rhamnose utilization. It exists in two anomeric forms, alpha-L-rhamnose and beta-L-rhamnose. Rhamnose has been found in Klebsiella, Pseudomonas ( (
