Retinol is one of the vitamins that the body requires for normal growth, development, and functioning. Chemically, retinol has a molecular formula of C20H30O, which forms a beta-ionone ring and isoprenoid chain with a functional alcohol group (-OH) at the terminal. The physical properties of retinol are that it is a crystalline yellow-orange solid at room temperature with melting and boiling points of 62-64oC and 137-138oC respectively. As a chemical property, retinol undergoes oxidation to form retinal and retinoic acid. Both plants and animals are sources of retinol as they produce carotenoids and preformed retinol accordingly. Although retinol is important in vision, regulation of translation, and dermatological use, excessive intake of retinol predisposes one to osteoporosis, cancer, congenital effects, and hormonal imbalance.
