Lycopene allows a reduction of reactive oxygen species (ROS), as it works as a mech-anism to prevent chronic diseases. This is achieved with the increase of lycopene levels in WebThe red form has an absorption peak at about 520 nm. That's at the edge of the cyan region of the spectrum, and the complementary color of cyan is red. Again, there's nothing unexpected here. Notice that the change from the yellow form to the red form has produced an increase in the wavelength absorbed.
