General description

L-Rhamnose is a part of plant cell wall polysaccharides, rhamnogalacturonan I and rhamnogalacturonan. It is also present in bacterial cell walland a major antigenic determinant contributing to its pathogenicity. L-rhamnose is non-absorbable in humans but is fermented by intestinal microbes. Supplementation of L-rhamnose slows down gastric emptying. L-rhamnose monosaccharide conjugated immunogens have applications in cancer immunotherapies. Intake of L-rhamnose elevates serum propionate levels.

Application

L-Rhamnose monohydrate has been used:
  • in biofilm enhancement assay in S.pneumonia
  • as a sugar drink in humans undergoing intestinal barrier permeability test
  • for the standard curve generation in high performance liquid chromatography(HPLC)
