A reducing disaccharide present in mammalian milk and consisting of a galactosyl residue linked B1,4 to a glucopyranose; obtained from cow's milk and used in modified milk preparation, in food for infants and convalescents, and in pharmaceutical preparations; in large doses, acts as an osmotic diuretic and as a laxative. Human milk contains 6.7% lactose.

A reducing disaccharide that is hydrolysed by beta-galactosidase into d-galactose and d-glucose; it is synthesised by mammalian mammaries, and causes intolerance to milk products that occurs in some adults.

milk sugar

a DISACCHARIDE carbohydrate found in the milk of mammals. Lactose is produced by a CONDENSATION REACTION between galactose and glucose. See Fig. 203 .

The sugar can be broken into its component monosaccharides by LACTASE. Souring of milk is due to the conversion of lactose to LACTIC ACID by microorganisms present in the milk.
