  • What's L-Rhamnose Monohydrate


L-Rhamnose Monohydrate is a naturally occurring deoxy sugar. It can be classified as either a methyl-pentoseor a 6-deoxy-hexose. Rhamnose occurs in nature in its L-form as L-rhamnose (6-deoxy-L-mannose). 

L-Rhamnose Monohydrate is also called α-L-Rhamnopyranose, 6-Dexoxy-D-mannose, 6-Deoxy-L-mannose, Isodulcite, L-Mannomethylose. Most of Rhamnose in nature is L-Rhamnose, existing in plants as the types of Polysaccharides, glycosides, plant gum and bacterial polysaccharides. 


L-Rhamnose Monohydrate is a methyl pentose sugar and has properly been classified as one of the rarer sugars. This sugar is a constituent of many glycosides. The rhamnoglycoside of quercetin (rutin) has been most often used as a source of rhamnose and after its hydrolisis, it yields the aglycon and L-Rhamnose Monohydrate. L-Rhamnose Monohydrate obtained by this method is a very pure crystalline powder, free from any visible impurities.  


L-Rhamnose Monohydrate finds use in the flavor industry as a starting material for the production of furanones, as wel as the starting raw material in reaction flavors developed during the preparation of various foods such as bread, grilled meats, etc 


L-Rhamnose Monohydrate appearance: White-crystal or white-crystal-powder;


L-Rhamnose Monohydrate solubility: soluble in water and methanol, slightly soluble in ethanol, shows in two types:α & β. 

L-Rhamnose Monohydrate type α contains a molecular water of crystallization,it will transform into type β(M.W.: 164.16) after dehydration by heating. 


L-Rhamnose Monohydrate type β with hygroscopic character, it will transform into type α after moisture absorption in the air.
