L-Mannose, 6-deoxy,

Deoxy-L-mannose (L-rhamnose) is common, but D-rhamnose has only been found in some 0-antigens, as in that of Pseudomonas cepacia IMV 3181, which is a homopolysaccharide containing both a- and y -pyranosyl residues.

Using conditions similar to those employed for the preparation of the polyglucoses, Mora and coworkers174 also polymerized other aldohexoses (D-galactose and D-mannose), two deoxy sugars (2-deoxy-D-ara mo-hexose and 6-deoxy-L-mannose), aldopentoses (L-arabinose, D-xylose, and D-ribose), and a disaccharide (maltose). Milder conditions were required for the deoxy sugars and the pentoses. The properties of these polymers are presented in Table IV.

Rhamnose (L-Rhamnose, 6-Deoxy-l-mannose, L-Mannomethylose or Isoldulcitol). 

Several deoxy sugars, notably 2-deoxy-D-mY/ o-pentose (2-deoxy-D-ribose) the sugar component of DNA, 6-deoxy-L-mannose (L-rhamnose), 6-deoxy-L-galactose (L-fucose), 6-deoxy-D-glucose (quinovose), and their derivatives, occur very widely in natural products. Also relevant are dideoxy and trideoxy sugars, such as 3,6-dideoxyhexoses, components of the antigenic determinants bacterial... 

Deoxy-L-galactose (L-fucose) and 6-deoxy-L-mannose (L-rhamnose). 

Monosaccharide units derived from oxidised or reduced sugars are important components of polysaccharides. The most important deoxy sugars are L-rhamnose (6-deoxy-L-mannose) and L-fucose (6-deoxy-L-galactose). Uronic acids are sugars in which the 6 position has been formally oxidised to a carboxylic acid, and form the major basis for anionic polysaccharides. Important...

Deoxy carbohydrates are usually aldoses. The most common deoxyhexoses are L-configured ( ) [e.g., 6-deoxy-L-mannose (rhamnose) and 6-deoxy-galactose (fucose)]. The all-important deoxypentose of DNA is 2-deoxy-D-iibose.
