Question

The sugar present in milk is:

Answer 1

Lactose:

1. The primary disaccharide in milk is lactose, which the enzyme lactase catabolizes into glucose and galactose.
2. Because it is found in dairy products in large concentrations, lactose—also known as milk sugar—is a significant energy source.
3. Galactose and glucose are the sources of the disaccharide sugar lactose.
4. Between galactose and glucose, there is a $\mathrm{\beta }-1\to 4$ linkage in the glycosidic chain.
5. About 2-8% of the weight of milk is lactose.
6. Mammal babies consume lactose-rich milk, which is further processed in the colon by the enzyme lactase.
