beta-Cryptoxanthin

C40H56O (552.4331)


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. A mono-hydroxylated xanthophyll that is a provitamin A precursor. See also: Corn (part of). A carotenol that exhibits antioxidant activity.

Zeaxanthin

(1R)-4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-18-[(4R)-4-hydroxy-2,6,6-trimethylcyclohex-1-en-1-yl]-3,7,12,16-tetramethyloctadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]-3,5,5-trimethylcyclohex-3-en-1-ol

C40H56O2 (568.428)


Zeaxanthin is a carotenoid xanthophyll and is one of the most common carotenoid found in nature. It is the pigment that gives corn, saffron, and many other plants their characteristic color. Zeaxanthin breaks down to form picrocrocin and safranal, which are responsible for the taste and aroma of saffron Carotenoids are among the most common pigments in nature and are natural lipid soluble antioxidants. Zeaxanthin is one of the two carotenoids (the other is lutein) 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 cataract (up to 20\\%) and for 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). Zeaxanthin has been found to be a microbial metabolite, it can be produced by Algibacter, Aquibacter, Escherichia, Flavobacterium, Formosa, Gramella, Hyunsoonleella, Kordia, Mesoflavibacter, Muricauda, Nubsella, Paracoccus, Siansivirga, Sphingomonas, Zeaxanthinibacter and yeast (https://reader.elsevier.com/reader/sd/pii/S0924224417302571?token=DE6BC6CC7DCDEA6150497AA3E375097A00F8E0C12AE03A8E420D85D1AC8855E62103143B5AE0B57E9C5828671F226801). It is a marker for the activity of Bacillus subtilis and/or Pseudomonas aeruginosa in the intestine. Higher levels are associated with higher levels of Bacillus or Pseudomonas. (PMID: 17555270; PMID: 12147474) Zeaxanthin is a carotenol. It has a role as a bacterial metabolite, a cofactor and an antioxidant. It derives from a hydride of a beta-carotene. Zeaxanthin is a most common carotenoid alcohols found in nature that is involved in the xanthophyll cycle. As a coexistent isomer of lutein, zeaxanthin is synthesized in plants and some micro-organisms. It gives the distinct yellow color to many vegetables and other plants including paprika, corn, saffron and wolfberries. Zeaxanthin is one of the two primary xanthophyll carotenoids contained within the retina of the eye and plays a predominant component in the central macula. It is available as a dietary supplement for eye health benefits and potential prevention of age-related macular degeneration. Zeaxanthin is also added as a food dye. Zeaxanthin is a natural product found in Bangia fuscopurpurea, Erythrobacter longus, and other organisms with data available. Carotenoids found in fruits and vegetables. Zeaxanthin accumulates in the MACULA LUTEA. See also: Saffron (part of); Corn (part of); Lycium barbarum fruit (part of).

C40H56O2 (568.428)


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.
