Just as there are three monosaccharid sugars with six carbon atoms
each, so there are three disaccharid sugars which have twelve carbon
atoms each. The first of these is cane-sugar. It is commercially made
from either sugar-cane or sugar-beets, and is identical in chemical
composition from either source.
Cane sugar, when digested in the human body, or by artificial means,
combines with water, and forms glucose and levulose, as shown by the
following equation:
C₁₂H₂₂O₁₁ + H₂O = C₆H₁₂O₆ + C₆H₁₂O₆
Cane-sugar + Water = Glucose + Levulose
