Carotene definition, any of three yellow or orange fat-soluble pigments having the formula C40H56, found in many plants, especially carrots, and transformed to vitamin A in the liver; provitamin A Carotene, any of several organic compounds widely distributed as pigments in plants and animals and converted in the livers of many animals into vitamin A. These pigments are unsaturated hydrocarbons (having many double bonds), belonging to the isoprenoid series Carotenoid is a huge family of pigments (colors) ranging from yellow to red in the plant kingdom, and they are predominantly found in fruits and vegetables. To date, there are more than 700 identified color pigments that can be classified into two classes - Carotenes and Xanthophylls [1,2]. The table below shows the properties for these two.
Carotenoids serve two key roles in plants and algae: they absorb light energy for use in photosynthesis, and they protect chlorophyll from photodamage. Carotenoids that contain unsubstituted beta-ionone rings (including beta-carotene, alpha-carotene, beta-cryptoxanthin and gamma-carotene) have vitamin A activity (meaning that they can be converted to retinol) What Are Melanin and Carotene? According to The Journal of Nutrition, melanin and carotene are two of three pigments that determine skin color. The third pigment is hemoglobin Carotene definition is - any of several orange or red crystalline hydrocarbon pigments (such as C40H56) that occur in the chromoplasts of plants and in the fatty tissues of plant-eating animals and are convertible to vitamin A . The name beta carotene comes from the Greek beta and Latin carota (carrot)
