Carrots are available in a rainbow of vibrant colours — pink, orange, yellow and purplish black — due to compounds known as carotenoids. They assist help eye well being by reacting with probably dangerous UV mild. Apparently, the molecular constructions of carotenoids, similar to beta-carotene, are much like the constructing blocks of some polymers. Now, researchers have included a compound derived from beta-carotene right into a polymer that is totally degradable.
