The bees drew the nectar by their labium, and pass it into their honey stomach which is a wonderful little factory. In that factory with the help of salivery enzyms, the cane sugar in the nectar is converted:ِ 1)into, ``DEXTROSE'' which is a kind of crystalline sugar (C6H12O6), occuring in many plants and in the animal organism.
2) Besides that, the small factory produces a second type of crystalline sugar out of the nectar which is called, ``LEVULOSE'' or fruit sugar, occuring with difficulty in the honey, and in the most of the sweet fruits. It is produced by inversion of, ``SUCROSE''.
Upon returning to the hive, the bee gushes back the partially processed nectar into a cell of the comb. It is worthy of note that this SUREH was revealed in Mecca where there was no plantation or flowers, nor bee and honey!
