Product Information

• Name: Lewis A trisaccharide
• Synonyms: 2-Acetamido-2-deoxy-4-O-(a-L-fucopyranosyl)-3-O-(b-D-glucopyranosyl)-D-glucopyranoseGal-b-1,3(Fuc-a-1,4)GlcNAc
• Brand: Biosynth
• Description: Lewis A is a trisaccharide that has been found to be present in the glycan structures of spermatozoa. It has also been identified as a major component of the glycan structures on the surface of HL-60 cells. Lewis A is composed of three monosaccharides, galactose, fucose, and N-acetylgalactosamine, which are linked together with a beta (1→4) linkage. The hydroxyl group on the galactose molecule allows for steric interactions with neighboring sugar molecules through hydrogen bonding and van der Waals forces. The Lewis A trisaccharide is an important marker for identifying blood type O because it does not have any antigenic determinants that can cause an immune response.
