Vitamin A is the common name for a group of fat-soluble substances present in two forms in food: preformed vitamin A (retinol and retinyl esters such as retinyl palmitate and retinyl acetate) and vitamin A precursor carotenoids (beta-carotene, alpha-carotene and many others) that the body converts into retinol or retinoic acid.
