HUMAN NUTRITION

Detailed explanation-1: -The basic monosaccharide units of lactose are glucose and galactose.

Detailed explanation-2: -Lactose: The sugar found naturally in milk, lactose is a disaccharide composed of one galactose molecule and one glucose molecule. Lactose is sometimes called “milk sugar.” Maltose: A disaccharide composed of two glucose molecules, maltose is found in molasses and is used in fermentation.

Detailed explanation-3: -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. This difference, however, gives galactose different chemical and biochemical properties to glucose.
