Pigments or biochrome are the substances present in all living
matter and play basic roles in the development of living organisms
including plants. Plants use these pigments for the variety of
functions including photosynthesis, signaling, to ward off
herbivores and attracting pollinating and dispersal agents. The
most common plant pigments are chlorophylls, carotenoids, betalains
and anthocyanins. In fact, chlorophylls are the most important
organic compounds, essential for photosynthesis. Carotenoids
presents in plants are usually play their roles in both nutrition
and photosynthesis and are necessary for the survival of both
mammals and plants. They also served as precursors of plant hormone
abscisic acid in higher plants. Another role of carotenoids is to
protect photosynthetic organisms against potentially harmful
photooxidative processes. Betalains are nitrogen containing water
soluble compound, belonging to the families of Caryophyllales,
except for Caryophyllaceae and Molluginaceae. Betalains are
classified into yellow betaxanthins and red betacyanins and are
immonium conjugates of betalamic acid. Anthocyanins are water
soluble vacuolar pigments belonging to flavonoids. They appear in
plants as blue, red or purple depending on the pH and synthesized
through phenylpropanoid pathway. As these plant pigments are of
many roles including structural to physiological functions in cells
therefore special consideration has been given in this book to
their salient characteristics, some biosynthesis and their chemical
and biochemical role in different fields. Special attention is also
given to specific role of these plant pigments in bioassays
regarding the human health. Methodological applications for these
pigments are also deeply demonstrated in few chapters including the
In silico study for diversifying the molecular pathway of pigment
formation.
