(p) Lycopene is the pigment present in the tomato that is responsible for the tomato's characteristic red color. In nature, most of the lycopene exists as all-frans isomer but hent, light and other forms of processing may convert some of this form of lycopene to the 13-cts isomer. 14 Lycopene 4) Draw the structure of 13-cis isomer.
