Vitamin A, chemical name as retinol, is the earliest vitamin being discovered. There are two types of Vitamin A: one is retinol which is the initial form of VA, it only exists in animals; another one is carotene. Retinol can be composited by -carotene coming from plants. Inside the body, under the catalysis of �²-carotene-15 and 15â?²-double oxogenase, �²-carotene is transformed into retinal which is returned to retinol by the performance of retinal reductase. Thus-carotene is also called as vitamin precursor. Function: -Retinol can effectively prevent obesity, keep women slim figure. -Retinol is used to promote bone growth, help teeth growth, regeneration. -Retinol can adjust the skin and cuticle metabolic effect, can be anti-aging, and to wrinkles. -Retinol can help protect skin, mucous membrane from bacteria violations, healthy skin, prevent skin cancer. -Retinol also can prevent nyctalopia, eyesight decline, the treatment of various eye disease, make the woman good eyes. -Retinol can reduce sebaceous overflow and make the skin elasticity, and at the same time, desalination spot, smooth skin Application 1.Prevent night blindness and vision loss; it's helpful to the treatment of eye diseases.
