Anwendungen & Verwendung
Occurrence
L-Fucose exists in nature in various biological niches. A major natural source of L-fucose is the brown algal polysaccharide fucoidan. It is also present in the polysaccharides of tragacanth, potatoes, kiwi, soybeans, varieties of wing peas, canola and other plants.L-Fucose is a minor component in plant cell wall polysaccharides, specifically rhamnogalacturonan, xyloglucan and also arabinogalactan proteins that are involved in plant cell elongation.
Verwenden
L-Fucose was isolated from seaweed. It finds application in cosmetics, pharmaceuticals and dietary supplements. It is used in the determination of antigen in A and B blood group. It is also used in the selection-mediated leukocyte-endothelial adhesion and host-microbe interactions. L-Fucose is also used in anti aging creams as well as to promote the accelerated healing of wounds and to reduce allergy.
