BIOMOLECULES AND ENZYMES

Detailed explanation-1: -With regard to minerals, lactose is known to enhance the absorption and retention of calcium, magnesium, and manganese; this is related to a pH drop due to its fermentation in the large intestine, which increases solubility of calcium (and other minerals), thereby increasing passive absorption.

Detailed explanation-2: -Carbohydrate. Milk is approximately 4.9% carbohydrate in the form of lactose. The lactose content of some milk varieties is shown in the Nutrient Content Tables. Carbohydrates are the primary source of energy for activity.

Detailed explanation-3: -Disaccharides are an important type of carbohydrate that are found in many foods. Lactose is one of the three major disaccharides. The other two are produced with different combinations of simple sugar monosaccharides: Maltose molecules are made up of two glucose molecules linked together.

Detailed explanation-4: -Lactose has been recognized as an enhancer of calcium absorption in mammals. The stimulating effect of lactose on calcium absorption is apparent in animal studies, but in humans such an effect is still controversial.
