Beta-carotene is FDA approved to be used as a nutrient supplement and to be even added in infant formula as a source of vitamin A. They are both symmetrical; the BASF synthesis is C20 + C20, and the Hoffman-La Roche synthesis is C19 + C2 + C19. The second is a Grignard reaction,[23] elaborated by Hoffman-La Roche from the original synthesis of Inhoffen et al. Carotene is an orange colored substance which can be digested to make vitamin A. Carnivores in general are poor converters of dietary ionone-containing carotenoids. All are coloured to the human eye, due to extensive systems of conjugated double bonds. Carotenes are also responsible for the orange (but not all of the yellow) colours in dry foliage. Add off- white painted trim and colorful graphic prints for the walls. Some carotenes are terminated by hydrocarbon rings, on one or both ends of the molecule. The results indicated an increased risk of lung and prostate cancers for the participants who consumed the β-carotene supplement and who had lung irritation from smoking or asbestos exposure, causing the trial to be stopped early.[13]. In Australia, organic β-carotene is produced by Aquacarotene Limited from dried marine algae Dunaliella salina grown in harvesting ponds situated in Karratha, Western Australia. β-Carotene is composed of two retinyl groups, and is broken down in the mucosa of the human small intestine by β-carotene 15,15'-monooxygenase to retinal, a form of vitamin A. β-Carotene can be stored in the liver and body fat and converted to retinal as needed, thus making it a form of vitamin A for humans and some other mammals.

Carotenes are also found in palm oil, corn, and in the milk of dairy cows,[citation needed] causing cow's milk to be light yellow, depending on the feed of the cattle, and the amount of fat in the milk (high-fat milks, such as those produced by Guernsey cows, tend to be yellower because their fat content causes them to contain more carotene). Carotene is an orange chemical, and it is what gives carrots their orange color.

Specifically, the group of nine carbon atoms at each end form a β-ring. [2] Along with several other carotenoids, γ-Carotene is a vitamer of vitamin A in herbivores and omnivores. Encapsulation increases chemical and thermal stability of carotene molecules; it also allows their isolation and individual characterization.[19]. © 2021 PPG Industries, Inc. All Rights Reserved. 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. Carotenemia or hypercarotenemia is excess carotene, but unlike excess vitamin A, carotene is non-toxic. Our CaroCare® solution offers a range of natural-source beta-carotene formulations that offer ease-of-use, superior color stability and guaranteed minimum color intensity. All other carotenoids, including lycopene, have no beta-ring and thus no vitamin A activity (although they may have antioxidant activity and thus biological activity in other ways). The two ends of the β-carotene molecule are structurally identical, and are called β-rings. The two primary isomers of carotene, α-carotene and β-carotene, differ in the position of a double bond (and thus a hydrogen) in the cyclic group at one end (the right end in the diagram at right). It provides them some relief from photosensitivity.[17]. Beta-carotene is an antenna pigment found in plants, algea and photosynthetic bacteria. Beta-carotene is the yellow/orange/red pigments found in vegetables and fruits with rich color. Beta-carotene is probably the best known of the largest family of pigments produced by nature, the Carotenoids. Le carotène, ou plutôt les carotènes car il en existe deux formes différentes, font partie de la famille des caroténoïdes, des pigments de couleur jaune, orange à rouge, présents entre autres dans les végétaux comme la carotte d'où provient son nom. β-carotene is the molecule that gives carrots, sweet potatoes, squash, and other yellow or orange vegetables their orange color. Some of the fruits, vegetables, herbs or nuts which have the highest content of beta carotene are given in the list below. Gamma-, delta-, epsilon-, and zeta-carotene (γ, δ, ε, and ζ-carotene) also exist. Beta-Carotene Beta-carotene is a member of the carotenoid family, known for its intense pigments. The typical yellow-coloured fat of humans and chickens is a result of fat storage of carotenes from their diets. Beta-carotene and other carotenoids provide approximately 50% of the vitamin A needed in the American diet. In Portugal, the industrial biotechnology company Biotrend is producing natural all-trans-β-carotene from a non-genetically-modified bacteria of the genus Sphingomonas isolated from soil. Beta-carotene is most abundant in carrots, of course, but is also found in pumpkins, apricots and nectarines.
