(Biochem.)
A crystalline disaccharide ({C12H22O11}) formed from starch
by the action of diastase of malt, and the amylolytic ferment
of saliva and pancreatic juice; called also {maltobiose} and
{malt sugar}. Chemically it is
4-O-[alpha]-D-glucopyranosyl-D-glucose. It rotates the plane
of polarized light further to the right than does dextrose
and possesses a lower cupric oxide reducing power.
