Carotenoids are a large class of isoprenoid pigments produced by plants and certain microbes. More than 700 naturally occurring carotenoids have been identified. Apocarotenoids are tailored from carotenoids by oxidative enzymes. Apocarotenoids act as visual or volatile signals to attract pollinating and seed dispersal agents. They are also the key players in allelopathic interactions and plant defense. provides detailed account of the fundamental chemistry of apocarotenoids and the basic methods used in carotenoid research, and critical discussions of the biochemistry, functions, and applications of these important compounds. Topics covered in the proposed book include various aspects of the roles of apocarotenoids in colour and colouration, photosynthesis and other photofunctions and protection. The formation and roles of carotenoid metabolites and breakdown products as perfume/aroma compounds are also be outlined.
