Vitamin A is a group of unsaturated nutritional organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, and beta-carotene. Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision.itamin A is needed by the retina of the eye in the form of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision.
Although vitamin A's chief function involves the eyes and vision, it also plays important roles in the development of bones, including the teeth. In addition, vitamin A aids immune function and helps provide a barrier against infections of the skin, lungs and mouth.
