Blood group B pentasaccharide

Galα1-3(Fucα1-2)Galβ1-4(Fucα1-3)Glc

This is a general term for a class of carbohydrate epitopes that function as antigens on the surface of red blood cells. Their pentasaccharide structures include a terminal galactose unit, which is the key component that defines the Type B blood group. These compounds are critical markers in blood typing and are involved in cell-cell recognition processes.
