Chemical Composition and Structure

Retinol is an organic compound that is compost of carbon, hydrogen, and oxygen. Essentially, retinol comprises of 20-carbon atoms, 30-hydrogen atoms, and an atom of oxygen. The molecular formula of retinol is C₂₀H₃₀O. The elements that are present in retinol combine to form a beta-ionone ring and isoprenoid chain, which are main the main components of retinol. The functional group of retinol is an alcohol group (-OH), which is attached at the terminal end of the isoprenoid. Moreover, retinol exists in all-trans form as shown below.
