(A transfusion of normal group O blood can trigger a severe transfusion reaction.). Because the H antigen is the precursor of the ABO blood group antigens, if it is not produced, the ABO blood group antigens are also not produced.f a person has blood group O, the H antigen remains unmodified. Therefore, the H antigen is present in the highest amounts in blood type O and in the least amounts in blood type AB. Two regions of the genome encode two enzymes with very similar substrate specificitiesâthe H locus (FUT1) and the Se locus (FUT2).
Today, very little honey is produced as comb honey. Comb honey is raw pure honey sections taken straight from the hive â honey bees' wax comb with no further handling at all. It is the most unprocessed form in which honey comes -- the bees fill the hexagon shaped wax cells of the comb with honey and cap it with beeswax.
One way to ensure real, pure honey is to go to your local farmers market and buy a container of real honey COMB - yes, the honey with comb intact is a sure way to tell if the honey is pure. I purchase mine from a local farmer who has his own hives and packages his own honey.
