[Sidenote: Maltose--how formed]
Maltose is the second member of the disaccharid group, and is of the
same composition as the other two. Maltose derives its name from malt.
It is formed from the starch of grains by a process of digestion which
may be performed in the animal body, or by the process of malting.
Maltose, like cane-sugar, can be further digested into monosaccharid
sugars, but upon such digestion, instead of forming two separate simple
sugars, it is wholly converted into glucose.
The reader will now understand the meaning of the terms _monosaccharid_,
_disaccharid_, and _polysaccharid_. MONO, which means _one_, is the
simplest form of carbohydrates. Disaccharids (DI, meaning _two_), split
up to form two simple sugars. Polysaccharids (POLY, meaning _many_) are
complex compounds which form many simple sugars.
