Beta-Carotene and Other Carotenoids Paperback – Janu by Richard A. Passwater (Author)4/5(1). Blood concentrations of carotenoids are the best biological markers for consumption of fruits and vegetables. A large body of observational epidemiological evidence suggests that higher blood concentrations of β-carotene and other carotenoids obtained from foods are associated with lower risk of several chronic diseases.
This evidence, although consistent, cannot be used to establish a. Because the beta-carotene in this supplement is derived from a natural source, trace amounts of other naturally occurring carotenoids are also present, although in clinically insignificant quantities. Of the total carotenoid content in each softgel, 95% (by weight) is beta-carotene, and % is s: 1.
It is not known to what extent this is true for vitamin C, vitamin E, selenium, or β-carotene and other carotenoids. However, adult men and women participating in NHANES III underreported energy intake by about 23 percent, as well as fat intake (which serves as a carrier for vitamin E) when expressed as a percentage of total energy intake.
This report focuses on vitamin C, vitamin E, selenium, and β-carotene and other carotenoids (α-carotene, β-cryptoxanthin, lutein, lycopene, and zeaxanthin). These compounds have frequently been called dietary antioxidants since in some cases they counteract oxidative damage to biomolecules (Halliwell, ), and the possibility exists that increased intakes of these compounds may protect.
β-Carotene and Other Carotenoids as Antioxidants. Carotenoids are natural pigments which are synthesized by plants and are responsible for the bright colors of various fruits and vegetables.
There are several dozen carotenoids in the foods that we eat, and most of these carotenoids have antioxidant by: Just one serving of Solaray Plant Source Food Carotene provi IU of Vitamin A as Beta Carotene, Alpha Carotene and other carotenoids (Cryptoxanthin, Zeaxanthin and Lutein).
Together, these carotenoids may work together to help support normal, healthy skin and eyes, antioxidant activity, and immune system function/5(3). The guidance I'm relying on, from Eating Well for Optimum Health: The Essential Guide to Food, Diet, and Nutrition among other resources, is that I should include a mixed carotenoid supplement which conta IU of beta carotene along with some alpha carotene, lutein, lycopene, and zeaxanthin/5(36).
There are several dozen carotenoids in the foods that we eat, and most of these carotenoids have antioxidant activity. Beta-carotene has been best studied since, in most countries it is the most common carotenoid in fruits and vegetables. However, in the U.S., lycopene from tomatoes now is consumed in approximately the same amount as by: Beta-carotene, the most abundant and efficient precursor of vitamin A, is a liposoluble antioxidant whose main activity occurs in collagen and elastin fibers (Wertz et al., ).
It is a carotenoid derived from natural food sources such as carrots, tomatoes, spinach, sweet potato, other yellow and green vegetables, fruits, and seaweeds (Bayerl, ).
β-Carotene, lycopene, and other carotenoids are widely distributed in human tissues, including the prostate [,], where, as potent antioxidants, they help protect cell membranes, DNA, and other macromolecules from damage by reactive oxygen species.

Washington, DC: The National Academies Press. doi: / The various biological effects of carotenoids can be classified. Beta Carotene. Beta-carotene (provitamin A) is the plant source of retinol from which mammals make two-thirds of their vitamin A.
Carotenoids, the largest of the vitamin A subclasses, contain multiple conjugated double bonds and exist in a free alcohol or in a fatty acyl-ester form.
Carotenoids containing some oxygen are known as xanthophylls. The two ends of the β-carotene molecule are structurally identical, and are called β-rings. Specifically, the group of nine carbon atoms at each end form a β-ring.
The α-carotene molecule has a β-ring at one end; the other end is called an ε-ring. There is no such thing as an Missing: book.

Although beta-carotene supplements are being studied for their ability to reduce the risk of certain types of cancer and possibly heart disease, there is not enough information to show that this is effective.
Beta-carotene may be used to treat other conditions as determined by your doctor. Beta-carotene is available without a prescription. Beta-Carotene Introduction Beta-carotene is one of many hundreds of food carotenoids, relatively only few of which have been studied in relation to their impact on human physiology.
Beta-carotene is the most abundant form of provitamin A in fruits and vegetables (Olson ; Ross ). The other twoFile Size: KB. Once ingested, beta-carotene is either converted into vitamin A (retinol), which the body can use in a variety of ways, or it acts as an antioxidant to help protect cells from the damaging effects of harmful free radicals.
As much as 50 percent of vitamin A in a typical diet is provided by beta-carotene and other g: book. Beta-carotene and other carotenoids provide approximately 50% of the vitamin A needed in the American diet. Beta-carotene can be found in fruits, vegetables, and whole grains.
It can also be made in a laboratory. Beta-carotene is used to prevent certain cancers, heart disease, cataracts, osteoarthritis, and age related macular degeneration (AMD). It can also be extracted from the beta-carotene rich algae, Dunaliella salina. The separation of β-carotene from the mixture of other carotenoids is based on the polarity of a compound.
β-Carotene is a non-polar compound, so it is separated with a non-polar solvent such as hexane.E number: Ea (colours). The Beta-Carotene & Vitamin A Mix-Up. Until recently, one of the only spoken of benefits of beta-carotene and other carotenoids, was that they could correct deficiencies in vitamin A.
Essential for healthy skin, proper growth and development, immune function and gene expression, vitamin A is often woefully missing in the Standard American Diet.
The results of clinical studies are not consistent with those of molecular researches. But other carotenoids, such as lycopene, alpha-and beta-carotene, are associated with pancreatic cancer r Therefore, a meta-analysis is necessary to clarify the association between vitamin A, retinol and carotenoids intake and pancreatic cancer by: Carotenoids are further classified into two groups i.e.
carotenes and xanthophylls. These kinds of carotenoids have antioxidant effect as well. Plus, some of these carotenoids such as alpha-carotene, beta-carotene, and beta-cryptoxanthin convert into vitamin A, which is essential for the health of children and adults g: book.

What beta carotene is: Beta carotene, like some other carotenoids (natural plant pigments found in many deep yellow/ orange fruits and vegetables), can be converted by the body into vitamin A, as is an antioxidant.
Claims, purported benefits: Prevents cancer and heart disease; boosts immunity; supports good vision. It is an ingredient in many eye-health supplements, including those Missing: book. The best known Carotenoids are Beta-Carotene, Lutein, and Lycopene. Beta-carotene has received a lot of attention as potential anti-cancer and anti-aging phytochemical.
Beta-carotene is a powerful antioxidant, protecting the cells of the body from damage caused by free g: book.
Beta-carotene, with the molecular formula C40H56, belongs to the group of carotenoids consisting of isoprene units.
The presence of long chains of conjugated double bonds donates beta-carotene with specific colors. It is the most abundant form of carotenoid and it is a precursor of the vitamin A. Beta-carotene is composed of two retinyl groups. Beta-carotene is an orange-coloured plant compound discovered in many fruits and veggies, especially carrots.
Like all other carotenoids, beta-carotene is a strong antioxidant able of scavenging potentially dangerous free radicals. Your physique can convert beta-carotene into retinol -- generally recognized as vitamin A -- if required. While offering multiple benefits, carotenoids play an even more important role to support the immune system.
Since humans cannot synthesise carotenoids like other immune molecules, we obtain carotenoids through our diets or via dietary supplements. The most prominent carotenoids in our diet and circulation are beta-carotene, lutein and lycopene. Beta-carotene, along with other carotenoids, is a powerful antioxidant agent that can scavenge free radicals, preventing them from damaging tissues and cells.
When combined with other antioxidants such as vitamins C and E, beta-carotene has been identified. Trans-β-carotene was the main carotenoid, followed by α-carotene, lutein and other minor carotenoids. It was found ± mgg-1 of gallic acid equivalent, ± mgg-1 of. Carotenoids serve two key roles in plants and algae: they absorb light energy for use in photosynthesis, and they provide photoprotection via non-photochemical quenching.
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).Missing: book. these foods include apricots, asparagus, beets, broccoli, cantaloupe, carrots, corn, green peppers, kale, mangoes, turnip and collard greens, nectarines, peaches Missing: book.

Carotenoids are pigments in plants, algae, and photosynthetic bacteria. These pigments produce the bright yellow, red, and orange colors in plants, vegetables, and : Kiara Anthony. Many clinical trials are underway to determine safety and effectiveness of different carotenoids, both alone and in combination with other drugs and supplements.
BETA-CAROTENE. Beta-carotene is a yellow-orange provitamin A carotenoid. Good sources of beta-carotene include carrots, sweet potatoes, winter squash, pumpkin, spinach, kale, and broccoli. Carotenosis is a benign and reversible medical condition where an excess of dietary carotenoids results in orange discoloration of the outermost skin discoloration is most easily observed in light-skinned people and may be mistaken for jaundice.: Carotenoids are lipid-soluble compounds that include alpha- and beta-carotene, beta-cryptoxanthin, lycopene, lutein, and lty: Dermatology.
