α-L-Rhamnopyranose 98% Purity Natural Sugar Reference Standard CAS 6014-42-2 Research Grade Monosaccharide

• • • • • Product Overview

          α-L-Rhamnopyranose, commonly known as L-rhamnose or 6-deoxy-L-mannose, is a naturally occurring methylpentose monosaccharide. It is a fundamental component of many plant-derived glycosides, bacterial polysaccharides, and glycoproteins. The compound exists predominantly in the pyranose ring form as shown by its name. With the molecular formula C₆H₁₂O₅ and a molecular weight of 164.16 g/mol, it appears as a white crystalline powder with a sweet taste. It is freely soluble in water and slightly soluble in alcohol. This compound is widely used as a reference standard in carbohydrate chemistry and as a chiral building block in organic synthesis.

          Natural Sources and Biosynthesis

          L-Rhamnose is ubiquitously distributed in nature as a component of plant cell wall pectins (rhamnogalacturonan I and II), bacterial lipopolysaccharides, and various plant secondary metabolites. It is biosynthesized from D-glucose through a nucleotide sugar pathway involving UDP-glucose as the precursor.

          Research Applications
