Carotenoids

A class of natural fat-soluble pigments found principally in plants, belonging to a subgroup of terpenoids containing eight isoprene units forming a C40 polyene chain. Carotenoids play an important potential role in human health by acting as biological antioxidants.


Highly pigmented fat-soluble compounds naturally present in many foods.


A general term for the wide variety of red and yellow compounds chemically related to carotene that are found in plant foods.


A class of natural occurring pigments.


A general term for a group of plant-produced pigments ranging in color from yellow to red and brown. The carotenes and the xanthophylls, orange to yellow in color, are the most common. Carotenoids are responsible for the coloration of certain plants (e.g., the carrot) and of some animals (e.g., the lobster). The carotenoid pigments are transferred to animals as an element in their foods. Carotenoids are composed of isoprene units (usually eight) which may be modified by the addition of other chemical groups on the molecule. The carotenes are of importance to higher animals because they are utilized in the formation of vitamin A.


Class of high unsaturated yellow to red pigments found widely in plants and animals.


Any of more than 600 yellow-orange pigments found in fruits and vegetables such as apricots, sweet potatoes, asparagus, carrots, cantaloupe, kale, tomatoes, and winter squash. Many of the carotenoids, which include beta carotene and lycopene, are thought to protect against heart disease and certain types of cancer.


A group of substances of red or yellow pigment that are found in animal fat and some plants.


Like flavonoids, a class of phytonutrients, or plant nutrients. Along with flavonoids, they are responsible for the bright colors in vegetables and fruits—in this case yellow and orange. They are antioxidant and have other health benefits.


Yellow or orange or red pigments found in plastids of plants.


Carotenoids are a group of plant chemicals (phytochemicals) that are yellow-orange pigments. They have antioxidant potential and many can be converted to vitamin A. As antioxidants, carotenoids may be important in reducing oxidative stress, which can be valuable for reducing muscle damage during exercise as well as protecting athletes from the development of chronic diseases that are promoted by oxidative stress.


Any one of a group of about 1(X) naturally occurring yellow to red pigments found mostly in plants. The group includes the carotenes.


One of a group of more than 500 yellow, orange, green, or red fat-soluble pigments found naturally in fruits and vegetables and acting as antioxidants in the body. About 50 carotenoids are precursors of vitamin A. Carotenoids that have health benefits are alpha carotene, lycopene, cryptoxanthan, zeaxanthan, and lutein.


Yellow or orange-red pigments whose name comes from carotene which is the first name of the series isolated from carrot.


A group of fat-soluble pigments (colors) found in plants or nutritional supplements that are known to have antioxidant properties.


A substance found in yellow and orange fruits and vegetables and in dark green, leafy vegetables. Carotenoids may reduce the risk of developing cancer.


Phytochemicals are compounds of biological activity that exhibit a potent capacity to act as antioxidants, thereby serving as a safeguard against various maladies. The presence of these bioactive substances is particularly marked in green vegetation that is deeply pigmented, as well as in fruits and vegetables that display vivid hues of red or orange.


Diverse red and yellow pigments, including beta-carotene, encompass a range of compounds that exhibit both vitamin A and antioxidant properties. These pigments serve as notable substances that contribute to the vibrant colors observed in various natural sources.
