description:
vitamin a acetate, chemical name as retinol acetate, 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 β-carotene coming from plants. inside the body, under the catalysis of β-carotene-15 and 15′-double oxygenase, β-carotene is transformed into ratinal which is returned to retinol by the performance of ratinal reductase. thus β-carotene is also called as vitamin precursor.
