galactoside

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·to·side

(gə-lăk′tə-sīd′)n. Any of a group of glycosides that yield galactose on hydrolysis.

ga·lac·to·side

(gă-lak'tō-sīd) A compound in which the H of the OH group on carbon-1 of galactose is replaced by an organic radical.
