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.

galactose

(gə-lăk′tōs′)
n.
A monosaccharide, C6H12O6, commonly occurring in lactose and in certain pectins, gums, and mucilages.

ga·lac·tose

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

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.

ga·lac·tose

(Gal) (gă-lak'tōs)
An aldohexose constituent of lactose, cerebrosides, gangliosides, and mucoproteins.

The use of stable isotopes of carbon to show the galactose oxidation profile has improved our knowledge of galactose metabolism. Isotope tracing has shown that both patients with variant genotype for galactosemia and healthy individuals synthesize similar quantities of galactose, and patients with more severe genotypes have a considerably reduced ability to metabolize the galactose that is produced.
Based on our results, HD improved hepatic blood flow and increase galactose metabolism.

The method is linear over a wide range of RBC concentrations and would be useful in biochemical genetic laboratories for monitoring the galactose burden in known classic galactosemic patients as well as in determining the extent of abnormal galactose metabolism in individuals with variant genotypes of the GALT gene.
