or milk sugar,
white crystalline disaccharide (see carbohydrate). It has the same empirical formula (C₁₂H₂₂O₁₁) as sucrose (cane sugar) and maltose but differs from both in structure (see isomer).

Galactose

A monosaccharide and a constituent of oligosaccharides, notably lactose, melibiose, raffinose, and stachyose. It is also known as d -galactose and cerebrose (see illustration). Agar, gum arabic, mesquite gum, larch arabo galactan, and a variety of other gums and mucilages contain d -galactose. See Agar, Monosaccharide

Structural formula for α - d -galactose

l -Galactose (enantiomorph of d -galactose) occurs in several polysaccharides, including agar, flaxseed mucilage, snail galactogen, and chagual gum. Since d -galactose is usually also present, hydrolysis of these polysaccharides produces dl -galactose. See Carbohydrate

Galactose

a monosaccharide; one of the most frequently encountered natural hexahydric alcohols, a hexose. It differs from glucose in the spatial position of the groups around the fourth carbon atom. Galactose is readily soluble in water and only slightly soluble in alcohol. It exists in aliphatic and cyclic (pyranose, or furanose) forms, which are in a state of tautomeric equilibrium:

In plant tissues galactose is a component of raffinose, melibiose, and stachyose, as well as polysaccharides — galactans, pectins, saponins, various gums and mucilages, gum arabic, and so on. In the animal and human body galactose is a component of lactose (milk sugar), galactogen, group-specific polysaccharides, cerebrosides, and muco-proteins. Galactose is part of many bacterial polysaccharides and can be fermented by so-called lactose yeast. In animal and plant tissues, galactose readily changes to glucose, which is more assimilated and can be converted to ascorbic and galacturonic acids.

galactose

[gə′lak‚tōs] (biochemistry) C₆H₁₂O₆ A monosaccharide occurring in both levo and dextro forms as a constituent of plant and animal oligosaccharides (lactose and raffinose) and polysaccharides (agar and pectin). Also known as cerebrose.

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.
