WebThe bright color of carrots and many other orange and yellow vegetables is caused by carotenoid molecules such as beta-carotene. Carotenoids are long, thin molecules with a string of carbon-carbon double bonds in a row. These bonds absorb light and give carotenoids their characteristic yellow color. Webrepresents the double bond (i.e., the π bond) between the two carbons. C C H H In butadiene, all four carbon atoms have a 2p orbital. ... Beta-carotene (depicted below) is responsible for the orange-red colour in carrots. Plants produce 109 metric tons beta-carotene per year.
