Carotene, a substance found in carrots and elsewhere, constitutes a building block in vitamin A, which is necessary for the body to grow. After identifying two different types of carotene along with other researchers, Richard Kuhn was able to establish the existence of a third type in 1933. He also conducted important research into related substances called carotenoids. His development of chromatographic techniques was important in the isolation and pure production of substances. Richard Kuhn also carried out important work with vitamins B2 and B6.
