Lactose, or milk sugar, is a disaccharide composed of galactose and glucose and has the molecular formula C 12 H 22 O 11. Lactose makes up around 2–8% of milk (by mass). The name comes from lact (gen. lactis ), the Latin word for milk, plus the suffix -ose used to name sugars.
Mutations are believed to interfere with the function of lactase, causing affected infants to have a severely impaired ability to digest lactose in breast milk or formula. [19] Lactose intolerance in adulthood is a result of gradually decreasing activity (expression) of the LCT gene after infancy, which occurs in most humans.
Lactase persistence or lactose tolerance is the continued activity of the lactase enzyme in adulthood, allowing the digestion of lactose in milk. In most mammals , the activity of the enzyme is dramatically reduced after weaning . [ 1 ]

Dairy products may upset the digestive system in individuals with lactose intolerance or a milk allergy. [7] [8] [9] People who experience lactose intolerance usually avoid milk and other lactose-containing dairy products, which may cause mild side effects, such as abdominal pain, bloating, diarrhea, gas, and nausea.
The lactose gives milk its sweet taste and contributes approximately 40% of the calories in whole cow's milk's. Lactose is a disaccharide composite of two simple sugars, glucose and galactose. Bovine milk averages 4.8% anhydrous lactose, which amounts to about 50% of the total solids of skimmed milk.
It is a dairy product produced by souring heavy cream. Snow cream: A cream-based dessert with one or more flavoring agents added or dessert in which snow is mixed with a sweetened dairy-based liquid to make an ice cream substitute.
