What is Beta-Carotene?
Beta-carotene is one of a group of natural chemicals known as carotenes or carotenoids, which are highly pigmented (red, orange, yellow), fat-soluble compounds naturally present in many fruits, grains, oils, and vegetables (green plants, carrots, sweet potatoes, squash, spinach, apricots, and green peppers).
Beta carotene is converted in the body to vitamin A. Vitamin A serves several biological functions including involvement in the synthesis of certain glycoproteins. Vitamin A deficiency leads to abnormal bone development, disorders of the reproductive system, xerophthalmia (a drying condition of the cornea of the eye), and ultimately death. It is also an antioxidant, like vitamins E and C.
Beta-carotene is converted to retinol, which is essential for vision and is subsequently converted to retinoic acid, which is used for processes involving growth and cell differentiation.

什么是β-胡萝卜素？
β—胡萝卜素是类胡萝卜素之一，属于天然化学物，也是橘黄色脂溶性化合物，天然的存在于多种水果、谷类、油和蔬菜（绿色植物，胡萝卜，红薯，南瓜，菠菜，杏和青椒）。
β-胡萝卜素会被人体转换成维生素A。维生素A提供多种生物能量，包括一些糖蛋白合成。缺乏维生素A会造成骨骼发育异常，生殖系统疾病，干眼症（一种眼角膜干燥的状况），最终可能导致死亡。它也如同维生素E和C，是一种抗氧化剂。
β-胡萝卜素转化为维生素A，对视觉很重要；随后转化成视黄酸，适用于成长与细胞分化过程中。
