What is lactose? Lactose is a
sugar
found in milk. It is a disaccharide made up of glucose and galactose units. It is broken down into the two parts by an enzyme called lactase.
Lactose is a type of sugar found in milk, cheese, ice cream, and other dairy products. Lactase, an enzyme in your stomach, breaks down lactose into 2 simple sugars:
glucose and galactose

).

monosaccharides galactose, glucose and fructose
are all reducing sugars. Disaccharides are formed from two monosaccharides and can be classified as either reducing or nonreducing.
Why does lactose is reducing sugar?
For the same reason lactose is a reducing sugar.
The free aldehyde formed by ring opening can react with Benedict’s solution
. Thus, a solution of lactose contains both the α and β anomer at the “reducing end” of the disaccharide. … The hydrolysis of lactose gives galactose and glucose.

milk sugar
. Nondairy milks, including oat, coconut, rice, and soy milk, contain other simple sugars, such as fructose (fruit sugar), galactose, glucose, sucrose, or maltose.
Which animal milk has the highest lactose content?
Sheep milk
has higher fat and protein contents than goat and cow milk; only buffalo and yak milk contain more fat. Sheep milk also generally has a higher lactose content than milk from cows, buffaloes and goats.
Which sugar is known as the milk sugar?
Lactose
, carbohydrate containing one molecule of glucose and one of galactose linked together. Composing about 2 to 8 percent of the milk of all mammals, lactose is sometimes called milk sugar. It is the only common sugar of animal origin.
