n (Elements & Compounds) another name for lactose

lac•tose

(ˈlæk toʊs)

n. 1. a disaccharide, C₁₂H₂₂O₁₁, present in milk, that upon hydrolysis yields glucose and galactose. 2. a white, crystalline, sweet, water-soluble commercial form of this compound obtained from whey and used in infant feedings, in confections and other foods, in bacteriological media, and in pharmacology as a diluent. Also called milk sugar. [1855–60; < Latin lact-, s. of lac milk + -ose²]

Milk sugar

A form of sugar found in mammals’ milk and now usually referred to as lactose. When an infant had to be bottle-fed, cows’ milk was sometimes fortified with extra milk sugar.

lactose

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.
