(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.
A mixture of sugars and other carbohydrates, honey is mainly fructose (about 38-55%) and glucose (about 31%), with remaining sugars including maltose, sucrose, and other complex carbohydrates. Its glycemic index ranges from 31 to 78, depending on the variety.dulteration of honey is the addition of other sugars, syrups or compounds into honey to change its flavor, viscosity, make it cheaper to produce, or to increase the fructose content in order to stave off crystallization.
