Plants
At the Plants, they are additional pigments of the Photosynthèse (they can is to transfer to the Chlorophylle luminous energy which they absorb in the ranges of the spectrum located between the purple one and the red = collecting role of light, is to take the energy of chlorophyl in particular in the event of excess of light = photoprotector role); they are contained in the Chloroplaste S, more particularly the Chromoplaste S.The carotenoids are synthesized by all the Algue S, all the house plants and by many Champignon S and Bactérie S (of which the Cyanobactéries). They are absorbed by the animals in their food. Some of them are largely used in agribusiness industry for their coloring properties, and also in industry Cosmétique or pharmaceutical for their properties Antioxydant be and their capacity of Photoprotection.
In the animal
The carotenoids stimulate the synthesis of antibody and are antioxydants. They are Précurseur S, Vitamine has for example.
