Detailed explanation-1: -Monosaccharides include glucose, galactose and fructose-all commonly found in food. Monosaccharides are single sugar molecules that are the building blocks for all other sugars and carbohydrates. Glucose, fructose and galactose are examples of these.

Detailed explanation-2: -Galactose is a monosaccharide and has the same chemical formula as glucose, i.e., C6H12O6. It is similar to glucose in its structure, differing only in the position of one hydroxyl group.

Detailed explanation-3: -Glucose and fructose are individual sugar units and are also called monosaccharides. Sucrose is a sugar molecule made up of both glucose and fructose so sucrose is called a disaccharide. We get our sugar naturally from whole foods and also in processed foods where sugar is added.

Detailed explanation-4: -The three main monosaccharides that we consume are fructose, galactose and glucose. These monosaccharides combine in various pairs to form the three disaccharides that are most important in human nutrition: lactose, maltose and sucrose.
