47 7.1 Carotenoids About 200 naturally abundant tetraterpenes are known as carotenoids, because all of them represent structural derivatives of β-carotene with 11 to 12 conjugated CC double bonds Tomatoes Carrots Minor constituent of Carrots, rare in other plants

48 7.1 Carotenoids Carotenoids occur in the leaves, shoots, and roots of all higher plants They serve as color filters for photosynthesis in the leaves of plants, giving rise to the yellow and red color of the leaves during fall Many fruits such as paprika contain various carotenoids The animal organism metabolizes carotenoids received with food, as it is unable to synthesize these compounds de novo Ultimately, carotenoids and their metabolites are found as chromoproteins Some carotenoids are vitamin A active in the human and mammal organisim
