Core antigen fragment in ABO blood group system.

Alpha-Tetrasaccharide belongs to the class of organic compounds known as oligosaccharides. These are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Alpha-Tetrasaccharide is soluble (in water) and a very weakly acidic compound (based on its pKa). Within the cell, Alpha-tetrasaccharide is primarily located in the cytoplasm.
