Chlorophylls and carotenoids

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 ]. WebThe differences between the chlorophylls of these major groups was one of the first clues that they were not as closely related as previously thought. Carotenoids are usually red, orange, or yellow pigments, and include the familiar compound carotene, which …
