Blood Group A tetrasaccharide type 2

This is a specific carbohydrate epitope that functions as an antigen on the surface of red blood cells. Its tetrasaccharide structure includes a terminal N-acetylgalactosamine unit, which is the key component that defines the Type A blood group. This compound is a critical marker in blood typing and is involved in cell-cell recognition processes.
