Below is the structural formula of lycopene, C₄₀H₅₆, a deep-red compound that is partially responsible for the red color of ripe fruits, especially tomatoes. Approximately 20 mg of lycopene can be isolated from 1 kg of fresh ripe tomatoes. How many of the carbon–carbon double bonds in lycopene have the possibility for cis-trans isomerism? Lycopene is the all-trans isomer.
