galactose

 [gah-lak´tōs]
a monosaccharide sugar of the aldose group, derived from lactose. d-galactose is found in lactose, in cerebrosides of the brain, in the sugar beet, and in many gums and seaweeds; l-galactose is found in flaxseed mucilage.
galactose tolerance test a laboratory test done to determine the liver's ability to convert the sugar galactose into glycogen. Two methods may be used. The oral method requires about 5 hours to complete, and the intravenous method, which is more accurate, requires about 2 hours. With the oral method, elimination of more than 3 g of galactose in the urine during a 5-hour period indicates liver damage. With the intravenous method, all galactose should have been eliminated from the blood 45 minutes after its injection.

ga·lac·tose (Gal),

(gă-lak'tōs),
An aldohexose found (in d form) as a constituent of compounds such as lactose, cerebrosides, gangliosides, and mucoproteins, in galactoside or galactosyl combination; an epimer of d-glucose.

n.
A monosaccharide, C6H12O6, commonly occurring in lactose and in certain pectins, gums, and mucilages.

ga·lac·tose

galactose

A monosaccharide sugar that is a constituent of LACTOSE, the main sugar of milk. Also known as cerebrose.

galactose

a monosaccharide CARBOHYDRATE that does not occur freely in nature, but is combined with GLUCOSE to form LACTOSE, a disaccharide sugar found in milk.

Galactose

One of the two simple sugars, together with glucose, that makes up the protein, lactose, found in milk. Galactose can be toxic in high levels.
