WebCarotenoids can protect chlorophyll from photooxidation damage caused by strong light, and they are an indispensable structural component of the photosynthetic antenna and reaction center complex. In addition, carotenoids are an important component of some pigment-protein complexes [ 5 ] and are the precursor of abscisic acid (ABA) [ 6 ].
