Detailed explanation-1: -The antigens expressed on the red blood cell determine an individual’s blood group. The main two blood groups are called ABO (with blood types A, B, AB, and O) and Rh (with Rh D-positive or Rh D-negative blood types).
Detailed explanation-2: -The blood groups are defined by the presence of specific carbohydrate sugars on the surface of red blood cells, N-acetylgalactosamine for the A antigen, and D-galactose for the B antigen.
Detailed explanation-3: -ABO blood grouping is based on differences in the type of glycoprotein (protein with carbohydrates attached) present on the surface of red blood cells. Type A individuals have type A glycoproteins; Type B individuals have type B glycoproteins; Type AB individuals have both; and Type O individuals have neither.
