The provitamin A carotenoids are obtained from plant sources and comprise some of the best sources of this vitamin. The provitamin As are found in deep green, yellow,and orange fruits and vegetables, such as carrots, spinach, broccoli, kale, collard and turnip greens, mangoes, apricots, nectarines, pumpkins, and sweet potatoes. <br/>Vitamin A belongs to a class of compounds referred to as the retinoids, which consist of four isoprenoid units joined in a head-to-tail manner. All double bonds in the isoprenoid units are implied to be in the E (trans) configuration unless stated otherwise. Currently, the term retinoid is applied to retinol and its naturally occurring derivatives plus synthetic analogs, which need not have vitamin A activity. Vitamin A is currently used as a generic descriptor for all retinoids that exhibit the biological activity of retinol, the original substance identified as vitamin A. The term vitamin A1 and all-trans retinol have been used to refer to retinol whereas vitamin A2 was used to refer to 3,4-dehydroretinol.
