Lutein is a common carotenoid xanthophyll found in nature. Carotenoids are among the most common pigments in nature and are natural lipid-soluble antioxidants. Lutein is one of the two carotenoids (the other is zeaxanthin) that accumulate in the eye lens and macular region of the retina with concentrations in the macula greater than those found in plasma and other tissues. Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two. A relationship between macular pigment optical density, a marker of lutein and zeaxanthin concentration in the macula, and lens optical density, an antecedent of cataractous changes, has been suggested. The xanthophylls may act to protect the eye from ultraviolet phototoxicity via quenching reactive oxygen species and/or other mechanisms. Some observational studies have shown that generous intakes of lutein and zeaxanthin, particularly from certain xanthophyll-rich foods like spinach, broccoli, and eggs, are associated with a significant reduction in the risk for cataracts (up to 20\\\\\%) and age-related macular degeneration (up to 40\\\\\%). While the pathophysiology of cataract and age-related macular degeneration is complex and contains both environmental and genetic components, research studies suggest dietary factors including antioxidant vitamins and xanthophylls may contribute to a reduction in the risk of these degenerative eye diseases. Further research is necessary to confirm these observations (PMID: 11023002). Lutein is a carotenol. It has a role as a food colouring and a plant metabolite. It derives from a hydride of a (6R)-beta,epsilon-carotene. Lutein is an xanthophyll and one of 600 known naturally occurring carotenoids. Lutein is synthesized only by plants and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach, kale and yellow carrots. In green plants, xanthophylls act to modulate light energy and serve as non-photochemical quenching agents to deal with triplet chlorophyll (an excited form of chlorophyll), which is overproduced at very high light levels, during photosynthesis. Lutein is a natural product found in Eupatorium cannabinum, Hibiscus syriacus, and other organisms with data available. Lutein is lutein (LOO-teen) is a oxygenated carotenoid found in vegetables and fruits. lutein is found in the macula of the eye, where it is believed to act as a yellow filter. Lutein acts as an antioxidant, protecting cells against the damaging effects of free radicals. A xanthophyll found in the major LIGHT-HARVESTING PROTEIN COMPLEXES of plants.

Astaxanthin (pronounced as-tuh-zan-thin) is a carotenoid. It belongs to a larger class of phytochemicals known as terpenes. It is classified as a xanthophyll, which means "yellow leaves". Like many carotenoids, it is a colorful, lipid-soluble pigment. Astaxanthin is produced by microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. Professor Basil Weedon was the first to map the structure of astaxanthin.; Astaxanthin is the main carotenoid pigment found in aquatic animals. It is also found in some birds, such as flamingoes, quails, and other species. This carotenoid is included in many well-known seafoods such as salmon, trout, red seabream, shrimp, lobster, and fish eggs. Astaxanthin, similar to other carotenoids, cannot be synthesized by animals and must be provided in the diet. Mammals, including humans, lack the ability to synthesize astaxanthin or to convert dietary astaxanthin into vitamin A. Astaxanthin belongs to the xanthophyll class of carotenoids. It is closely related to beta-carotene, lutein, and zeaxanthin, sharing with them many of the general metabolic and physiological functions attributed to carotenoids. In addition, astaxanthin has unique chemical properties based on its molecular structure. The presence of the hydroxyl (OH) and keto (CdO) moieties on each ionone ring explains some of its unique features, namely, the ability to be esterified and a higher antioxidant activity and a more polar nature than other carotenoids. In its free form, astaxanthin is considerably unstable and particularly susceptible to oxidation. Hence it is found in nature either conjugated with proteins (e.g., salmon muscle or lobster exoskeleton) or esterified with one or two fatty acids (monoester and diester forms), which stabilize the molecule. Various astaxanthin isomers have been characterized on the basis of the configuration of the two hydroxyl groups on the molecule. the geometrical and optical isomers of astaxanthin are distributed selectively in different tissues and that levels of free astaxanthin in the liver are greater than the corresponding concentration in the plasma, suggesting concentrative uptake by the liver. Astaxanthin, similar to other carotenoids, is a very lipophilic compound and has a low oral bioavailability. This criterion has limited the ability to test this compound in well-defined rodent models of human disease. (PMID: 16562856); Astaxanthin is a carotenoid widely used in salmonid and crustacean aquaculture to provide the pink color characteristic of that species. This application has been well documented for over two decades and is currently the major market driver for the pigment. Additionally, astaxanthin also plays a key role as an intermediary in reproductive processes. Synthetic astaxanthin dominates the world market but recent interest in natural sources of the pigment has increased substantially. Common sources of natural astaxanthin are the green algae Haematococcus pluvialis, the red yeast, Phaffia rhodozyma, as well as crustacean byproducts. Astaxanthin possesses an unusual antioxidant activity which has caused a surge in the nutraceutical market for the encapsulated productand is) also, health benefits such as cardiovascular disease prevention, immune system boosting, bioactivity against Helycobacter pylori, and cataract prevention, have been associated with astaxanthin consumption. Research on the health benefits of astaxanthin is very recent and has mostly been performed in vitro or at the pre-clinical level with humans. (PMID: 16431409); Astaxanthin, unlike some carotenoids, does not convert to Vitamin A (retinol) in the human body. Too much Vitamin A is toxic for a human, but astaxanthin is not. However, it is a powerful antioxidant; it is claimed to be 10 times more capable than other carotenoids.

Astaxanthin is used in fish farming to induce trout flesh colouring. Astaxanthin is a carotenone that consists of beta,beta-carotene-4,4-dione bearing two hydroxy substituents at positions 3 and 3 (the 3S,3S diastereomer). A carotenoid pigment found mainly in animals (crustaceans, echinoderms) but also occurring in plants. It can occur free (as a red pigment), as an ester, or as a blue, brown or green chromoprotein. It has a role as an anticoagulant, an antioxidant, a food colouring, a plant metabolite and an animal metabolite. It is a carotenone and a carotenol. It derives from a hydride of a beta-carotene. Astaxanthin is a keto-carotenoid in the terpenes class of chemical compounds. It is classified as a xanthophyll but it is a carotenoid with no vitamin A activity. It is found in the majority of aquatic organisms with red pigment. Astaxanthin has shown to mediate anti-oxidant and anti-inflammatory actions. It may be found in fish feed or some animal food as a color additive. Astaxanthin is a natural product found in Ascidia zara, Linckia laevigata, and other organisms with data available. Astaxanthin is a natural and synthetic xanthophyll and nonprovitamin A carotenoid, with potential antioxidant, anti-inflammatory and antineoplastic activities. Upon administration, astaxanthin may act as an antioxidant and reduce oxidative stress, thereby preventing protein and lipid oxidation and DNA damage. By decreasing the production of reactive oxygen species (ROS) and free radicals, it may also prevent ROS-induced activation of nuclear factor-kappa B (NF-kB) transcription factor and the production of inflammatory cytokines such as interleukin-1beta (IL-1b), IL-6 and tumor necrosis factor-alpha (TNF-a). In addition, astaxanthin may inhibit cyclooxygenase-1 (COX-1) and nitric oxide (NO) activities, thereby reducing inflammation. Oxidative stress and inflammation play key roles in the pathogenesis of many diseases, including cardiovascular, neurological, autoimmune and neoplastic diseases.

beta-Cryptoxanthin has been isolated from abalone, fish eggs, and many higher plants. beta-Cryptoxanthin is a major source of vitamin A, often second only to beta-carotene, and is present in fruits such as oranges, tangerines, and papayas (PMID: 8554331). Frequent intake of tropical fruits that are rich in beta-cryptoxanthin is associated with higher plasma beta-cryptoxanthin concentrations in Costa Rican adolescents. Papaya intake was the best food predictor of plasma beta-cryptoxanthin concentrations. Subjects that frequently consumed (i.e. greater or equal to 3 times/day) tropical fruits with at least 50 micro g/100 g beta-cryptoxanthin (e.g. papaya, tangerine, orange, watermelon) had twofold the plasma beta-cryptoxanthin concentrations of those with intakes of less than 4 times/week (PMID: 12368412). A modest increase in beta-cryptoxanthin intake, equivalent to one glass of freshly squeezed orange juice per day, is associated with a reduced risk of developing inflammatory disorders such as rheumatoid arthritis (PMID: 16087992). Higher prediagnostic serum levels of total carotenoids and beta-cryptoxanthin were associated with lower smoking-related lung cancer risk in middle-aged and older men in Shanghai, China (PMID: 11440962). Consistent with inhibition of the lung cancer cell growth, beta-cryptoxanthin induced the mRNA levels of retinoic acid receptor beta (RAR-beta) in BEAS-2B cells, although this effect was less pronounced in A549 cells. Furthermore, beta-cryptoxanthin transactivated the RAR-mediated transcription activity of the retinoic acid response element. These findings suggest a mechanism of anti-proliferative action of beta-cryptoxanthin and indicate that beta-cryptoxanthin may be a promising chemopreventive agent against lung cancer (PMID: 16841329). Cryptoxanthin is a natural carotenoid pigment. It has been isolated from a variety of sources including the petals and flowers of plants in the genus Physalis, orange rind, papaya, egg yolk, butter, apples, and bovine blood serum. In a pure form, cryptoxanthin is a red crystalline solid with a metallic lustre. It is freely soluble in chloroform, benzene, pyridine, and carbon disulfide. In the human body, cryptoxanthin is converted into vitamin A (retinol) and is therefore considered a provitamin A. As with other carotenoids, cryptoxanthin is an antioxidant and may help prevent free radical damage to cells and DNA, as well as stimulate the repair of oxidative damage to DNA. Structurally, cryptoxanthin is closely related to beta-carotene, with only the addition of a hydroxyl group. It is a member of the class of carotenoids known as xanthophylls. Beta-cryptoxanthin is a carotenol that exhibits antioxidant activity. It has been isolated from fruits such as papaya and oranges. It has a role as a provitamin A, an antioxidant, a biomarker and a plant metabolite. It derives from a hydride of a beta-carotene. beta-Cryptoxanthin is a natural product found in Hibiscus syriacus, Cladonia gracilis, and other organisms with data available.

C40H56 (536.4381776)


alpha-Carotene belongs to the class of organic compounds known as carotenes. These are a type of unsaturated hydrocarbons containing eight consecutive isoprene units. They are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. alpha-Carotene is considered to be an isoprenoid lipid molecule. alpha-Carotene is one of the primary isomers of carotene. Plasma levels of alpha-carotene are positively associated with the detection rate of AFB1-DNA adducts in a dose-dependent manner, whereas plasma lycopene level was inversely related to the presence of the adducts in urine (PMID: 9214602). (6R)-beta,epsilon-carotene is an alpha-carotene. It is an enantiomer of a (6S)-beta,epsilon-carotene. alpha-Carotene is a natural product found in Hibiscus syriacus, Scandix stellata, and other organisms with data available.

Neoxanthin belongs to the class of organic compounds known as xanthophylls. These are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Xanthophylls arise by oxygenation of the carotene backbone. Neoxanthin is an intermediate in the synthesis of abscisic acid from violaxanthin. Neoxanthin has been detected, but not quantified in, several different foods, such as apples, paprikas, Valencia oranges, kiwis, globe artichokes, sparkleberries, hard wheat, and cinnamon. This could make neoxanthin a potential biomarker for the consumption of these foods. Neoxanthin has been shown to exhibit apoptotic and anti-proliferative functions (PMID: 15333710, 15333710). Neoxanthin is a carotenoid and xanthophyll. In plants, it is an intermediate in the biosynthesis of the plant hormone abscisic acid. It is produced from violaxanthin by the action of neoxanthin synthase. It is a major xanthophyll found in green leafy vegetables such as spinach.

(3R,3R,6R,9-cis)-beta,epsilon-Carotene-3,3-diol is a carotenoid found in human fluids such as serum and breast milk (PMID: 9164160). Carotenoids are isoprenoid molecules that are widespread in nature and are typically seen as pigments in fruits, flowers, birds and crustacea. Animals are unable to synthesise carotenoids de novo, and rely upon the diet as a source of these compounds. Over recent years there has been considerable interest in dietary carotenoids with respect to their potential in alleviating age-related diseases in humans. This attention has been mirrored by significant advances in cloning most of the carotenoid genes and in the genetic manipulation of crop plants with the intention of increasing levels in the diet. Studies have shown an inverse relationship between the consumption of certain fruits and vegetables and the risk of epithelial cancer. Since carotenoids are among the micronutrients found in cancer preventive foods, detailed qualitative and quantitative determination of these compounds, particularly in fruits and vegetables and in human plasma, have recently become increasingly important (PMID: 1416048, 15003396).

Lycoxanthin is a member of the class of compounds known as xanthophylls. Xanthophylls are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Lycoxanthin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Lycoxanthin can be found in eggplant and garden tomato (variety), which makes lycoxanthin a potential biomarker for the consumption of these food products.

Meso-zeaxanthin (3R,3´S-zeaxanthin) is a xanthophyll carotenoid, as it contains oxygen and hydrocarbons, and is one of the three stereoisomers of zeaxanthin. Of the three stereoisomers, meso-zeaxanthin is the second most abundant in nature after 3R,3´R-zeaxanthin, which is produced by plants and algae. To date, meso-zeaxanthin has been identified in specific tissues of marine organisms and in the macula lutea, also known as the "yellow spot", of the human retina . Meso-zeaxanthin is a member of the class of compounds known as xanthophylls. Xanthophylls are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Meso-zeaxanthin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Meso-zeaxanthin can be found in channel catfish, crustaceans, and fishes, which makes meso-zeaxanthin a potential biomarker for the consumption of these food products.
