(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.
The star of this syrup concoction, of course, is the raw honey, which has not been pasteurized or filtered, and ideally is taken directly from the hive. Not all honey is the same-you know this by simply looking at the honey and smelling it.Honey that is full of pollen will be heavier than the same amount of honey without the pollen, and its smell will be rich and heavy. The honey quality depends on the amount of pollen found in the nectar the bees gather.Local honey contains all of the local pollens (some of which are irritants or allergens to us).he best news about the presence of pollen in the honey is its change in taste-it has almost a body to it (like wine). There are many subtle variations in honey made all over the world.
