Step-by-step explanation:
Maltose and lactose are both disaccharides, which means they are composed of two sugar units. Maltose is made up of two glucose molecules, while lactose is made up of one glucose molecule and one galactose molecule.
Both maltose and lactose are used as sources of energy in the body. They are broken down into their individual sugar components by enzymes during digestion.
Additionally, both maltose and lactose are found in certain food sources. Maltose is commonly found in grains, while lactose is found in milk and dairy products.
