Explanation:
Detailed explanation-1: -Galactose is a monosaccharide sugar. Lactose, a disaccharide containing a molecule of galactose and glucose, is found in human and bovine milk.
Detailed explanation-2: -Is lactose a monosaccharide or disaccharide? Lactose is a disaccharide because it is made up of two monosaccharide molecules bonded together with a covalent bond. The monosaccharides that make up lactose are glucose and galactose.
