D-Galactose is a component of sugars such as agar, plant gums, mucilage, raffinose, lactose, and melibiose. It exists as galactoside and galactan molecules in animal materials such as snail glands, frog eggs, and brain nerve tissue. In its free form, it is found in milk. It combines with glucose to form lactose. Oxidation with nitric acid yields mucoacid.
