Lactose is a type of sugar which is found in milk and which is sometimes added to food. a type of sugar found in milk, sometimes used as a food for babies and sick people (lac ( LACTIC) + -ose). Slightly sweet sugar (disaccharide) composed of two monosaccharides, glucose and galactose, linked together. Lactose-intolerant adults, and more rarely infants, cannot digest lactose because they lack the enzyme (lactase) that splits it into simpler sugars and suffer diarrhea and bloating when they eat foods containing it. Lactose, which makes up 2-8% of the milk of mammals, is the only common sugar of animal origin. Commercial lactose is obtained from whey, a liquid by-product of cheese. It is used in foods, in pharmaceuticals, and in nutrient broths used to produce penicillin, yeast, and riboflavin, and other products
Also called "milk sugar," lactose is that sugar that occurs naturally in milk It is less sweet than any of the other sugars Used in baby formulas and candies
the sugar produced by animals and human being found in milk Lactose is broken down in our digestive system by the help of an enzyme protein called lactase
It has a slightly sweet taste, is dextrorotary, and is much less soluble in water than either cane sugar or glucose
a sugar comprising one glucose molecule linked to a galactose molecule; occurs only in milk; "cow's milk contains about 4 7% lactose"
