HUMAN NUTRITION

Detailed explanation-1: -Other disaccharides, such as sucrose and lactose are broken down by sucrase and lactase, respectively. Sucrase breaks down sucrose (or “table sugar”) into glucose and fructose, and lactase breaks down lactose (or “milk sugar”) into glucose and galactose.

Detailed explanation-2: -The disaccharides are broken down into monosaccharides by enzymes called maltases, sucrases, and lactases, which are also present in the brush border of the small intestinal wall.

Detailed explanation-3: -Explanation: Lactose is a disaccharide that needs to be broken down to its monosaccharide components in the gut (so that it can be absorbed). Lactose is made up of galactose and glucose monosaccharide units. An enzyme called lactase, found on the intestinal walls, is used to break down lactose to galactose and glucose.

Detailed explanation-4: -The enzyme that speeds up the digestion of lactose is called lactase.
