(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.
This process removes all impurities such as pollen and wax. Most generic brands of honey are usually ultra-filtrated. And this is our first tip. Stay away from honey that is labeled ultra-filtrated. Why? Pollen, removed by the ultra-filtration process, is the only way to determine the source of the honey. So when the pollen is removed, it can be from the US, China or somewhere else. No one knows. Some countries, especially China, have been known to smuggle honey into the United States.
