D-Galactose is a right-handed six-carbon aldose, with a chemical formula of C6H12O6. Appearance is white crystal or crystalline powder, no special smell, soluble in water, solubility in water: 680 g/L (25°C). D-galactose is a component of agar, plant gum, viscose, raffinose, lactose, melibiose and other sugars, and exists in snail protein glands, frog eggs, and cranial nerves as galactose and galactose anhydride molecules In animal materials such as tissues. The free state is found in milk. Combines with glucose to form lactose. Some derivatives of galactose are widely distributed in the plant kingdom. For example, galacturonic acid is the main component of plant mucus, and the main component of agaric gum (also known as agar) is a high polymer of galactose derivatives. Galactose has a slightly sweet taste after producing lactose. It can be used to make baby food, candy and margarine, and can be used as a flavoring agent in medicine.
