Relative to common carotenoids are carotenoids carrying a charge on the polyene chain particularly unstable and represent special challenges. These compounds play an important role in plant health. Carotenes are … Carotenoids seem to have been diversified largely by bacteria. A previous work, the Key to Carotenoids (1987, 2nd edition, Birkhäuser Publishing), listed complete literature references to 563 carotenoids obtained from natural sources up to 1982; this list was extended in an appendix to Carotenoids Vol. Carotenoids belong to the category of tetraterpenoids (i.e., they contain 40 carbon atoms, being built from four terpene units each containing 10 carbon atoms). Other apocarotenoids are involved in the interaction of plants with their biological environment, acting as pigments and flavors that attract pollinators or seed-dispersing animals (Giuliano et al., 2003; Bouvier et al., 2005b; Auldridge et al., 2006; Walter and Strack, 2011). Please refer our original paper in detail. Structural chemical formula and molecule model. Our search similar carotenoids using Carotenoid DB Chemical Fingerprints similarity score is given as follows. All biological functions investigated here are listed at http://carotenoiddb.jp/Biological_activity/biological_activities_list.html. Currently, the industrial production is executed through chemical synthesis, but natural alternatives of carotenoid production/attainment are in development. The end-to-end cyclization of lycopene polyene chain results in the production of carotenes and is the first branch point in the biosynthesis of complex carotenoids and xanthophylls. Lutein is found in large concentration in green leafy vegetables, such as lettuce (between 171 and 3824 μg/100 g), basil (from 3650 to 8270 μg/100 g), parsley (4326 μg/100 g), garden rocket (7440 μg/100 g), and cilantro (7703 μg/100 g). Carotenoids and xanthophylls E 160a Beta-carotene C 40 H 56 Canaries — — — — 30. Carotenoids are a chemically diverse group (>600 different compounds) of yellow to red colored polyenes consisting of 3–13 conjugates double bonds and in some cases, six carbon hydroxylated ring structures at one or both ends of the molecule. β-Carotene is also found, achieving 14,600 μg/100 g [25–27]. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003. (22). Also, the Carotenoid DB Chemical Fingerprints have made it easy to predict six biological functions of carotenoids, that is (i) provitamin A, (ii) membrane stabilizers, (iii) odorous substances, (iv) allelochemicals, (v) antiproliferative activity against cancer cells and (vi) reverse MDR activities. Updated information on the distribution of chemical modification details at phylum level is available at ‘http://carotenoiddb.jp/stats/org_statistics_phylum.html’. Once lipoproteins reach tissues, cellular receptors induce the absorption of carotenoids and promote degradation of lipoproteins. It is believed secondary hydroxyl group in xanthophylls undergoes enzymatic oxidative reactions and forms keto-carotenoids in mammals [36]. Published by Oxford University Press. The B-Carotene Molecule -- Chemical and Physical Properties . Some structure/activity relationships are considered. In the first months breast milk and/or formula preparations are the only nutrition for infants. (9Z)-β-carotene and lutein were not found in Archaea to our current knowledge. The fingerprints also allow (i) easier prediction of six biological functions of carotenoids: provitamin A, membrane stabilizers, odorous substances, allelochemicals, antiproliferative activity and reverse MDR activity against cancer cells, (ii) easier classification of carotenoid structures, (iii) partial and exact structure searching and (iv) easier extraction of structural isomers and stereoisomers.

Due to structural features of carotenoids related with oxygenated β-ionone ring, low-density lipoproteins transport carotenes (α-carotene, β-carotene, and lycopene), whereas high-density lipoproteins circulate xanthophylls (β-cryptoxanthin, lutein, and zeaxanthin) in blood stream [37]. Source references are all listed in carotenoid entries and organism entries. Tomato contains several bioactive compounds [24]. Plant carotenoids also take part in light harvesting and are vital for photoprotection against excess light. This physical property is due to a polyene chain with a large number of conjugated double bonds that acts as a chromophore. The general name for a group of fat-soluble pigments found in green, yellow, and leafy vegetables, and yellow fruits. Carotenoids are a class of plant chemicals and are found in the cells of a wide variety of plants. (, IUPAC Commission on the Nomenclature of Organic Chemistry and the IUPAC-IUB Commission on Biochemical Nomenclature (, Nakamura Y.Afendi F.M.Parvin A.K. Bendich A (1990) Carotenoids and the immune system. This root vegetable is a good source of important nutrients, including dietary fibers, vitamins, carbohydrates, and minerals [21]. In our current investigation, seco, nor, cyclo, olide carotenoids, geranylgeranyl and complex structure polymerized carotenoids are only observable in eukaryotes. We use cookies to help provide and enhance our service and tailor content and ads. The possibility of cis and trans configurations in these polyene structures give rise to enormous diversity in carotenoids but the vast majority of them in nature appear to have an all-trans configuration. The proposed reason for loss of antioxidant activity with increasing oxygen concentrations involves the formation of carotenoid peroxyl radicals that autoxidizes into additional free radicals. (, Nupur L.N.U.Vats A.Dhanda S.K. The fingerprints in every category vary in number of atoms, so we weighted each category of fingerprints to give weighted Tanimoto coefficient (19), inversely proportional to the occurrence rate, with a few exceptions. Structures of isoprene, carotenoids and apocarotenoids. Mixed carotenoids may contain fats, oils and waxes naturally occurring in the plant material. Even though the method was developed for five carotenoids, representing both carotenes and xanthophylls, the full-scan principle of the Orbitrap-MS offers to screen all known carotenoids and to search for unknown compounds, which are closely involved in carotenoid metabolism. Introduction. Scheme 14. To promote understanding of how organisms are related via carotenoids, either evolutionarily or symbiotically, or in food chains through natural histories, we built the Carotenoids Database. A few Notes on the chemical structure of Carotenoids Carotenoids may vary in chain length, but the majority contain forty carbon atoms (C 40 ). Several isomeric forms (same formula but different molecular structures) are subsumed under the name. β-CD: carotenoid oxidative cleavage. Initiation of lipid oxidation by singlet oxygen is due to its electrophillic nature, which will allow it to add to the double bonds of unsaturated fatty acids leading to the formation of lipid hydroperoxides. In the last half of the twentieth century, by using various biochemical and molecular approaches, the main carotenoid biosynthetic pathway was revealed. Yisong Guo, ... Madison Davidson, in Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2020. Bacteria then may have added six chemical modifications, that is, alkoxylation, ketolation, aldehyde attachment, carboxylation, sodium addition, and retro (a shift of all single and double bonds of the conjugated polyene chain). (, Gagez A.-L.Thiery V.Pasquet V. et al. 4.13). Google Scholar Bendich A (1994) Recent advances in clinical research involving carotenoids. [49] have reported that prolonged exposure of carrots to direct sunlight in the open field after harvest leads to the reduction in carotenoid content. Carotenoids may support the immune system by supporting the production of specific types of white blood cells. We use Open Babel (http://openbabel.org/wiki/Main_Page) to generate InChI, InChIKey and Canonical SMILES. LICHTENTHALER, H.K. Only the following solvents may be used for the extraction: methanol, ethanol, propan-2-ol, hexane, acetone, dichloromethane and methyl ethyl ketone. Fuentes et al. This review gives 158 literature references, including 126 references since 1990. Carotene, any of several organic compounds widely distributed as pigments in plants and animals and converted in the livers of many animals into vitamin A.These pigments are unsaturated hydrocarbons (having many double bonds), belonging to the isoprenoid series. Fingerprints can be categorized into 23 chemical modification patterns, namely, hydroxylation, saturation, cyclization of end groups, ketolation, desaturation, stereoisomer (RS), apo (cleavage of polyene chain), epoxidation, esterification, cis/trans isomerization, glycosidation, aldehyde-addition, alkoxylation, carbonylation, isoprene polymerizations, nor (elimination of CH3, CH2 or CH group), complex polymerization, olide formation, sulfation, seco formation (fission of the bond between two adjacent carbon atoms with addition of one or more hydrogen atoms at each terminal group), retro (a shift of all single and double bonds of the conjugated polyene chain), cycloaddition and geranylgeranyl polymerization in the descending order of frequency to our current statistics at the release of December 2016. It is worth noting that lycopene absorption is enhanced in tomato products due to increase in softness and change in isomerization from cis to trans in lycopene structure [24,28]. Other sources of dietary lycopene are guava and papaya [29,30]. Grains were milled on a laboratory mill. The method which we use is that of Goodwin(1965)- Chemistry and Biochemistry of plant pigments,1965, Academic Press, London. Charged carotenoids are treated in a systematic manner in this first comprehensive survey of the topic. Carotenoid anions including anion radicals and dianions are less studied. Beta-carotene is the molecule that gives carrots their orange color. The numbering of carotenoids in the Handbook is the same as that used throughout the Carotenoids volumes. In carrots, the α-carotene content ranges between 2538 and 8100 μg/100 g and β-carotene from 5977 to 12,700 μg/100 g [22,23]. Although the numbers of organisms we could compile are not evenly distributed in the three domains of life (Archaea: 8, Bacteria: 170 and Eukaryotes: 505), and not all the carotenoid entries could be linked to source organisms in the time so far available, our statistics on distribution in organisms show some insights into natural history. Category of carotenoids and including Carotenoid DB Chemical Fingerprints.

Methods for characterisation include CV, NIR, EPR, ENDOR and resonance Raman spectroscopy. Carotenoids Tweet. However, fishes like salmon and other animals acquire carotenoids through diet. Carotenoid-containing foods are often red, yellow or orange, but not always. Lycopene is the major carotenoid found in tomato and products elaborated from tomato. acetateextract richin carotenoids was evaporatedin a rotary evap-Table 1 Surface-active ionic liquids and anionic surfactants information: full name, acronyms, chemical formula, molecular mass, CMC and chemical structures. These position numbers follow the Nomenclature of Carotenoids approved by the IUPAC and IUB commissions (11). To achieve other tissues, carotenoids are transported by lipoproteins in plasma. Retail storage of carrots often takes place at a temperature range between 18 and 22°C. Synthesized by bacteria, fungi, Chemical structures are hand drawn with the chemical drawing tools Marvinsketch (https://www.chemaxon.com/products/marvin/marvinsketch/) and KegDraw (http://www.kegg.jp/kegg/download/kegtools.html). The process by which the plants, some bacteria, and some other protistans use the energy from the sunlight and produce glucose from carbon dioxide and water is called as Photosynthesis. Beta-carotene is an organic compound and is classified as a hydrocarbon, specifically as a terpenoid. We simplified them into three steps; first, by carbon numbers: C30, C40, C45 and C50 carotenoids, second, by end-groups, of which there are seven: ψ, β, γ, ε, φ, χ and κ, and third, by chemical modification pattern, that is, hydrocarbons, hydroxycarotenoids, epoxycarotenoids, aldehydes, ketones, carboxylic acids, apocarotenoids, norcarotenoids, secocarotenoids, retrocarotenoids, olidecarotenoids, allenecarotenoids, acetylenecarotenoids and diapocarotenoids. The phyla of source organisms producing each end group with carbon numbers are listed in Table 5. Carotenoids are a class of phytonutrients ("plant chemicals") and are found in the cells of a wide variety of plants, algae and bacteria. See the profile comparisons at http://carotenoiddb.jp/search_similar_profiled_organisms.cgi?keyword=Cyanidioschyzon%20merolae. Carotenoids are lipid-soluble pigments, which can be found in many kinds of fruit, vegetables, fungi, flowers and some kinds of animals (Ötles and Çagindi, 2008). The basic structure of carotenoids as exemplified by β-carotene is shown in Fig. . José M. Lorenzo, Paulo E. Munekata, in Studies in Natural Products Chemistry, 2016. Carotenoids are classified on their chemical composition as either carotenes or xanthophylls. This paper gives in Table F4.33 examples of the Chl and carotenoid content in leaves, as well The glucose formed can be converted into pyruvate which would releases adenosine triphosphate (ATP) by the cellular respiration. The enzymatic addition of single molecule of DMAPP with the three molecules of IPP results in the formation of geranylgeranyl diphosphate (GGPP), a key precursor for the biosynthesis of large number of plastidial isoprenoids including carotenoids (Lichtenthaler, 1999; Bouvier et al., 2005a,b). Classification of carotenoids using Carotenoid DB Chemical Fingerprints. CAS Number: 14660-91-4 Carotenoid, any of a group of nonnitrogenous yellow, orange, or red pigments (biochromes) that are almost universally distributed in living things. According the data available to us up to the time of the December 2016 release, the common carotenoids in the three domains of life shown in Figure 4 are only hydrocarbons: phytoene, 15-cis-phytofluene, all-trans-phytofluene, lycopene, β-carotene, (13Z)-β-carotene and α-carotene. Carotenoid cation radicals are involved in photosynthesis and in antioxidant reactions. Further, apocarotenoids are capable of modulating gene expression, apart from their antioxidant properties [46]. Total and individual carotenoid content in carrot wastes (dry weight), Kakali Mukherjee, ... Pulok K. Mukherjee, in Evidence-Based Validation of Herbal Medicine, 2015. Further, environmental conditions during growth and packaging alter the level of carotenoids. That is, both species have the same simple carotenoid profile: β-carotene and zeaxanthin, which is called ZEA-type by Takaichi et al. 6(CO2) + 6 (H2O) yeilds C6H12O6 + 6(O2) ... Carotenoids … The number in the fingerprints indicates the position-number of the chemically modified carbon atom. Mixed carotenoids are obtained by solvent extraction of alfalfa, removal of chlorophylls through saponification and subsequent purification of the carotenoids by solvent extraction. Nine or more conjugated double bonds are necessary for physical quenching, with the presence of six carbon oxygenated ring structures at the end the molecule increasing the effectiveness of singlet oxygen quenching. There are two major types: the hydrocarbon class, or carotenes, and the oxygenated (alcoholic) class, or xanthophylls. The important and diverse physiological functions of carotenoid derivatives,169 for example in vision, immunology, cancer, light harvesting, pathogen virulence, and pigmentation, have stimulated great interest in the characterization of CCOs and mechanistic studies as well. Empirical Formula (Hill Notation): C 40 H 56 O 4. 36-88-4 - Carotenoids - Searchable synonyms, formulas, resource links, and other chemical information. Its chemical formula is C 40 H 56 O 2. Pure Appl Chem 66:1017–1024 . Thermal, physical, or enzymatic disruption of fruits and vegetables generally increases release of carotenoids and dispersion during digestion [34]. All fingerprints and their detailed descriptions including the definitions of end groups are listed at ‘http://carotenoiddb.jp/Entries/Carotenoid_DB_Chemical_Fingerprint_Help.pdf’. According to Carotenoids Handbook (3), about 30 well-assigned natural carotenoids plus another 30–40 non-fully characterized carotenoids were compiled by Paul Karrer and Ernst Jucker in 1948. The data content of carotenoid entries (December 2016 release). . By this combination of fingerprints and weighted Tanimoto coefficient, we obtained more precise results than with conventional fingerprints in the chemical space of carotenoids within short computational times. 1A. Examples of CCO-catalyzed reactions. LC-HRMS has been used for the analysis of carotenoids from various plants [12,64,65,71]. (22) and Tomitani et al. Concentration of lycopene in raw tomato ranges between 32 and 27,100 μg/100 g of fresh weight. Carotenoids have various biological functions including their role as antioxidants. Comparisons with other, conventional fingerprints were done by calculating Tanimoto coefficients of all to all pairs of Carotenoids DB entries. In general, carotenoids in foods are classified into carotenes and xanthophylls, i.e., oxygenated carotenoids fraction, which gives attractive red or yellow color and contributes to food quality. Fig. Our fingerprints are unique in including positional information. This is also the case for microscale reactions useful for identification (1). Carotenoid definition is - any of various usually yellow to red pigments (such as carotenes) found widely in plants and animals and characterized chemically by … Krishnaswamy, ... Latha Periyasamy, in, Journal of Photochemistry and Photobiology B: Biology. Another structural feature of most carotenoid molecules is the presence of cyclic end groups [43]. Due to its high bioactivity, it is also widely used in medicine. The most notable feature of carotenoids is their conjugated polyene chromophores. The basic molecular structure of most carotenoids consists of a polyisoprenoid carbon chain with a series of conjugated double bonds located in the central portion of the molecule. developed a rapid carotenoid screening method with the reversed-phase UHPLC-HRMS [72]. Structures of carotenoids and xanthophylls. Before the end of the century, by the characterization and isolation of carotenoid-defective mutants from plants (Arabidopsis, tomato), algae (Chlamydomonas sp. For example, in the carotenoid profile of a cyanobacterium ‘Nostoc commune’ at ‘http://carotenoiddb.jp/ORGANISMS/Nostoc_commune.html’, the list of all carotenoids in the Nostoc genus is available at ‘http://carotenoiddb.jp/ORGANISMS/Nostoc.html’, and a list of all carotenoids in the Nostocaceae family is available at ‘http://carotenoiddb.jp/ORGANISMS/Nostocaceae.html’. The biological functions of carotenoids are influenced by their chemical structure. β-Carotene can be metabolized in enterocytes to produce vitamin A; however, for xanthophylls carotenoids, their metabolism remains not fully elucidated. These photoactivated molecules can promote oxidation by direct interactions with an oxidizable compounds to produce free radicals, by transferring energy to triplet oxygen to form singlet oxygen or by transfer of an electron to triplet oxygen to form the superoxide anion. These pigments have been used mainly in food, pharmaceutical, and cosmetic industries. Carotenoids are the likely precursor of a significant fraction of marine dissolved organic matter Neal Arakawa,1 Lihini I. Aluwihare,1* Andre J. Simpson,2 Ronald Soong,2 Brandon M. Stephens,1 Daniel Lane-Coplen2 The ocean’s biota sequester atmospheric carbon dioxide (CO 2) in part by producing dissolved organic matter (DOM) that persists in the ocean for millennia. Therefore, carotenoids with fingerprint ‘5,6-Epoxy’ or ‘5,8-Epoxy’ with and/or without prime, and ‘beta,beta’ are predicted as possible antiproliferative agents against cancer cells.
