Bycomparing the carbon skeletons of ß-carotene and lycopene, the similarities and the differences between them should be determined. Concept Introduction: Lycopene(C 4 0 H 5 6 ) is a bright red pigment and phytochemical found in red fruits and vegetables like tomatoes, carrots, etc. but not in cherries or strawberries. It is a free radical fighting antioxidant, and it helps in the protection against cancer. ß-carotene, (C 4 0 H 5 6 ) is a precursor to vitamin A. It is used as a food color because of the yellow color. This compound is found in plants in combination with chlorophyll and assist in the harvesting sunlight or energy.
