The Carotenoids Database looks pretty cool!
According to the site it “currently provides information on 1182 natural carotenoids in 700 source organisms..

A recent review paper, [Rodriguez-Concepcion, M., Avalos, J., Bonet, M. L., Boronat, A., Gomez-Gomez, L., Hornero-Mendez, D., … & Ribot, J. (2018). A global perspective on carotenoids: Metabolism, biotechnology, and benefits for nutrition and health. Progress in lipid research, 70, 62-93.]
Carotenoids are isoprenoid metabolites synthesized by all photosynthetic organisms (including plants, algae and cyanobacteria) and some non-photosynthetic archaea, bacteria, fungi and animals. In photosynthetic systems, carotenoids participate in light harvesting and they are essential for photoprotection
In addition, carotenoids can be cleaved to produce compounds with roles as growth regulators, such as abscisic acid (ABA) and strigolactones, as well as bioactive molecules. Most animals (including humans) do not synthesize carotenoids de novo but take them in the diet and use them as essential precursors for the production of retinoids such as vitamin A. Additionally; carotenoids have been proposed to confer other health benefits whose discovery is spurring their use in functional food products.
