Detailed explanation-1: -Galactose is a monosaccharide and has the same chemical formula as glucose, i.e., C6H12O6.
Detailed explanation-2: -Lactose is a disaccharide consisting of glucose and galactose and is found naturally in milk.
Detailed explanation-3: -Galactose is derived from the breakdown of lactose. Lactose is the disaccharide of milk and milk‐containing products. Lactose is hydrolyzed to glucose and galactose by lactase in humans (Reichardt & Berg, 1988; Valle et al., 2019).
Detailed explanation-4: -Lactose is a disaccharide, which means it is made up of two sugar molecules, or monosaccharides. This molecule is the main sugar present in milk and dairy products (cheese, yogurt, butter, etc.). It is found in the milk of all placental mammals, including humans.
