responsible for red colour found in tomatoes‚ grapes‚ watermelon‚ and other bright colored fruits and vegetables. Its function in plants is to absorb light in photosynthesis and to protect plants from the excess of light1. Lycopene is an acyclic isomer of β-carotene with 11 conjugated double bonds‚ normally in the all-trans configuration. Because its double bonds are conjugated‚ lycopene absorbs radiation at long wavelength of the visible spectrum2. Lycopene has been characterized as a strong antioxidant

the enzyme to interact in a specific way leading to a chemical reaction involving the substrate to take place and appropriate products will be formed. Enzymes are highly specific and so they have the ability to distinguish between pairs of optical isomers (and this is important in this case). A close match between the structure of the substrates and the outline of the active site helps achieve this. However‚ enzymes are proteins and since proteins are not rigid‚ some enzymes are able to fold around
