    D-galactose CAS 59-23-4 is a type of D-hexaldose obtained by hydrolysis of lactose, with the chemical formula C6H12O6. The appearance is white crystal or crystalline powder, without special odor, soluble in water and pyridine, with a solubility of 680 g/L (25 ° C) in water; Slightly soluble in glycerol and alcohol. D-galactose is a component of sugars such as agar, plant gum, mucus, and raffinose, lactose, and melibiose. It exists in animal materials such as snail protein glands, frog eggs, and brain nerve tissue as molecules of galactoside and galactose. Free state can be found in milk. It combines with glucose to form lactose. After oxidation with nitric acid, mucus acid can be obtained.
