C40H56 (536.4382)


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. Widespread carotenoid, e.g. in carrots and palm oil. Has vitamin A activity but less than that of b-Carotene A cyclic carotene with a beta- and an epsilon-ring at opposite ends respectively.

Zeaxanthin

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).

Mangiferol, also known as alpizarin or chinomin, is a member of the class of compounds known as xanthones. Xanthones are polycyclic aromatic compounds containing a xanthene moiety conjugated to a ketone group at carbon 9. Xanthene is a tricyclic compound made up of two benzene rings linearly fused to each other through a pyran ring. Mangiferol is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Mangiferol can be found in mango, which makes mangiferol a potential biomarker for the consumption of this food product. Mangiferin is a Nrf2 activator. Mangiferin suppresses nuclear translocation of the NF-κB subunits p65 and p50. Mangiferin exhibits antioxidant, antidiabetic, antihyperuricemic, antiviral, anticancer and antiinflammatory activities[1][2][3]. Mangiferin is a Nrf2 activator.

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.
