Detailed explanation-1: -Lactose is the major disaccharide found in milk, and is catabolized into glucose and galactose by the enzyme lactase. Lactose is an important energy source and ssometimes it is referred to simply as milk sugar, as it is present in high percentages in dairy products.

Detailed explanation-2: -Lactose, often called milk sugar (Latin, lac, milk), is a disaccharide found in the milk of many mammals, including humans and cows. The IUPAC name of lactose is 4-O-(-d-galactopyranosyl)-d-glucopyranose. Given its somewhat jawbreaking name, it is easy to see why it is called simply lactose.

Detailed explanation-3: -Lactose is the sugar component of milk, which is why it is referred to as “milk sugar.” It is present in milk produced by cows, sheep, goats, and other mammals, including human breast milk. It is a disaccharide composed of the monosaccharides glucose and galactose.
