Definition: sugar of milk
lactose
\lac"tose`\ (l[a^]k"t[=o]s`), n.
1. (Physiol. Chem.) The main sugar present in milk, called
also
sugar of milk or
milk sugar. When isolated pure
it is obtained crystalline; it is separable from the whey
by evaporation and crystallization. It is a disaccharide
with the formula
C12H22O11, being chemically
4-([beta]-D-galactosido)-D-glucose. It has a slightly
sweet taste, is dextrorotary, and is much less soluble in
water than either cane sugar or glucose. Formerly called
lactin. When hydrolyzed it yields glucose and galactose.
In cells it may be hydrolyzed by the enzyme
[beta]-galactosidase.
