Which type of sugar is prevalent in milk?

The sugar that is prevalent in milk is galactose. Galactose is one of the two monosaccharides that combine to form lactose, the primary sugar found in milk. Lactose is crucial for providing energy, especially to infants, as it aids in the absorption of calcium and other nutrients. When lactose is digested, it is broken down into glucose and galactose, but galactose remains significant as a component of lactose itself in milk. Understanding the role of galactose in dairy products is essential for studying nutrition, particularly regarding lactose intolerance and dietary recommendations for individuals who are unable to digest lactose effectively.
