galactose (redirected from galactose 1-phosphate uridylyl transferase)

galactose /ga·lac·tose/ (gah-lak´tōs) a six-carbon aldose epimeric with glucose but less sweet, occurring naturally in both d- and l- forms (the latter in plants). It is a component of lactose and other oligosaccharides, cerebrosides and gangliosides, and glycolipids and glycoproteins.

n.

A monosaccharide commonly occurring in lactose. Also called brain sugar.

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.

galactose

[gəlak′tōs]

Etymology: Gk, gala + glykys, sweet

a simple sugar found in the dextrorotatory form in lactose (milk sugar), nerve cell membranes, sugar beets, gums, and seaweed and in the levorotatory form in flaxseed mucilage. Prepared galactose, a white crystalline substance, is less sweet and less soluble in water than glucose but is similar in other properties.

galactose (glak´tōs),

n a simple sugar found in the dextrorotatory form in lactose (milk sugar), nerve cell membranes, sugar beets, gums, seaweed, and, in the levorotatory form, in flaxseed mucilage. Galactose, a white crystalline substance, is less sweet and less soluble in water than glucose but is similar in other properties.

galactose

a monosaccharide derived from lactose. d-galactose is found in lactose, cerebrosides of the brain, raffinose of the sugar beet, and in many gums and seaweeds; l-galactose is found in flaxseed mucilage.

galactose 1-phosphate uridylyl transferase

involved in the metabolism of galactose to glycogen. Congenital galactosemia of humans and macropods is associated with a deficiency of this enzyme.

galactose tolerance test

a laboratory test done to determine the liver's ability to convert the sugar galactose into glycogen. Not much used in animals.
