The process of photosynthesis always begins with the absorption of light energy. This is done by certain pigments called photosynthetic pigments in plants and cyanobacteria. These pigments are of various types like chlorophyll, phycobilins, carotenoids and certain sunscreen pigments like mycosporine like amino acids (MAAs) and scytonemin. These pigments are mainly involved in the absorption of light energy and also they have certain defence mechanisms like antioxidant property which is helpful in protection of plant or cell against the environmental stress. In this review, the role of photosynthetic pigments and their protection against oxidative damage by antioxidant activity is discussed.
