The carrot gets its characteristic and bright orange colour from â-carotene, which is partly metabolised into vitamin A in humans. Carotene is responsible for the orange colour of carrots and many other fruits and vegetables. The term carotene (also carotin, from the Latin carota, or carrot) is used for several related unsaturated hydrocarbon substances having the formula C40Hx, which are synthesized by plants but cannot be made by animals. Carotene is an orange photosynthetic pigment important for photosynthesis. Carotenes are all coloured to the human eye. They are responsible for the colours of many other fruits and vegetables (for example, sweet potatoes and orange cantaloupe melon).
