(gcide) | 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.
[1913 Webster +PJC]
2. (Chem.) See Galactose.
[1913 Webster]Maltose \Malt"ose`\ (m[add]lt"[=o]s`), n. [From Malt.]

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.
[1913 Webster +PJC]Sugar \Sug"ar\, n. [OE. sugre, F. sucre (cf. It. zucchero, Sp.
az['u]car), fr. Ar. sukkar, assukkar, fr. Skr. [,c]arkar[=a]
sugar, gravel; cf. Per. shakar. Cf. Saccharine, Sucrose.]
1. A sweet white (or brownish yellow) crystalline substance,
of a sandy or granular consistency, obtained by
crystallizing the evaporated juice of certain plants, as
the sugar cane, sorghum, beet root, sugar maple, etc. It
is used for seasoning and preserving many kinds of food
and drink. Ordinary sugar is essentially sucrose. See the
Note below.
[1913 Webster]
Note: The term sugar includes several commercial grades, as
the white or refined, granulated, loaf or lump, and the
raw brown or muscovado. In a more general sense, it
includes several distinct chemical compounds, as the
glucoses, or grape sugars (including glucose proper,
dextrose, and levulose), and the sucroses, or true
sugars (as cane sugar). All sugars are carbohydrates.
See Carbohydrate. The glucoses, or grape sugars, are
ketone alcohols of the formula C6H12O6, and they turn
the plane of polarization to the right or the left.
They are produced from the amyloses and sucroses, as by
the action of heat and acids of ferments, and are
themselves decomposed by fermentation into alcohol and
carbon dioxide. The only sugar (called acrose) as yet
produced artificially belongs to this class. The
sucroses, or cane sugars, are doubled glucose
anhydrides of the formula C12H22O11. They are usually
not fermentable as such (cf. Sucrose), and they act
on polarized light.
[1913 Webster]
2. By extension, anything resembling sugar in taste or
appearance; as, sugar of lead (lead acetate), a poisonous
white crystalline substance having a sweet taste.
[1913 Webster]
3. Compliment or flattery used to disguise or render
acceptable something obnoxious; honeyed or soothing words.

[1913 Webster]Sucrose \Su"crose`\, n. [F. sucre sugar. See Sugar.] (Chem.)
A common variety of sugar found in the juices of many plants,
as the sugar cane, sorghum, sugar maple, beet root, etc. It
is extracted as a sweet, white crystalline substance which is
valuable as a food product, and, being antiputrescent, is
largely used in the preservation of fruit. Called also
saccharose, cane sugar, etc. At one time the term was
used by extension, for any one of the class of isomeric
substances (as lactose, maltose, etc.) of which sucrose
proper is the type; however this usage is now archaic.
[1913 Webster +PJC]
Note: Sucrose proper is a dextrorotatory carbohydrate,
C12H22O11. It does not reduce Fehling's solution, and
though not directly fermentable, yet on standing with
yeast it is changed by the diastase present to invert
sugar (dextrose and levulose), which then breaks down
to alcohol and carbon dioxide. It is also decomposed to
invert sugar by heating with acids, whence it is also
called a disaccharate. Sucrose possesses at once the
properties of an alcohol and a ketone, and also forms
compounds (called sucrates) analogous to salts. Cf.
Sugar.
