Question

Quizplus · Accepted Answer

The A and B antigens in human blood are produced by the conversion of the H antigen through the addition of specific sugar groups. The A antigen is created by adding N-acetylgalactosamine to the H antigen, while the B antigen is formed by adding another sugar, galactose, to the H antigen. This process is enzyme-mediated and determines an individual's blood type in the ABO blood group system.
