Vitamin C is a white crystal or crystalline powder. Its melting point is 190℃~192℃, no odour and sour taste. It is easily dissoved in water, slightly dissovled in ethanol and not dissovled in chloroform and diethyl ether. Vitamin C is a kind of soluble vitamin and has very strong reducibility. It is easy to break down when heat or in the solution. And it is easier to be oxidized in alkaline conditions. Vitamin C in food is absorbed by the upside of small intestine. Once absorbed, it will spread in to the soluble stuctures of the body.
