Detailed explanation-1: -Answer and Explanation: The disaccharide composed of glucose and galactose joined by a glycosidic bond is called lactose. Lactose is found in dairy products such as milk and is broken down into glucose and galactose through the action of an enzyme called lactase. A deficiency of lactase can lead to lactose intolerance.
Detailed explanation-2: -Maltose, or malt sugar, is a disaccharide made up of two glucose molecules. The most common disaccharide is sucrose (table sugar), which is made of glucose and fructose.
Detailed explanation-3: -lactose, carbohydrate containing one molecule of glucose and one of galactose linked together. Composing about 2 to 8 percent of the milk of all mammals, lactose is sometimes called milk sugar. It is the only common sugar of animal origin.
Detailed explanation-4: -Lactase breaks down lactose into the monosaccharides galactose and glucose, which makes them available for absorption. Glucose ultimately gets taken up by our cells with the help of insulin. Galactose is transported to the liver, where it is turned into glucose for use in energy production.
