José M. Lorenzo, Paulo E. Munekata, in Studies in Natural Products Chemistry, 2016. Zeaxanthin is usually observed in lower concentration compared to other dietary carotenoids cited above and is also reported in fewer vegetables and fruits compared to lutein, although pepper and scallions display elevate concentration of zeaxanthin (1665 and 2488 μg/100 g, respectively) [26]. Beta-carotene is an organic compound and is classified as a hydrocarbon, specifically as a terpenoid. Further, environmental conditions during growth and packaging alter the level of carotenoids. Likewise, epoxycarotenoids having β,β or β,κ or β,ε end groups (Capsochrome, for example) function as reverse MDR agents against cancer cells (25). Chemical name Lutein: 3,3'-dihydroxy-d-carotene; ß,epsilon-carotene-3,3'-diol C.A.S. The number in the fingerprints indicates the position-number of the chemically modified carbon atom. These Carotenoid DB Chemical Fingerprints describe the chemical substructure and the modification details based upon International Union of Pure and Applied Chemistry (IUPAC) semi-systematic names of the carotenoids. There are two major types: the hydrocarbon class, or carotenes, and the oxygenated (alcoholic) class, or xanthophylls. Eukaryotes then probably have evolved a considerable number of C40 carotenoids. Accessory pigments include chlorophyll b (also c, d, and e in algae and protistans), carotenoids (such as beta-carotene) and xanthophylls. The basic structure of carotenoids as exemplified by β-carotene is shown in Fig. Figure 3.4. CAS Number: 14660-91-4 This explains human brain localization of tocopherol (0.11–17 nmol/g), carotenoids (1.8–23 pmol/g) and retinol (87.8–163.3 pmol/g) [39]. . (24). Classification of carotenoids using Carotenoid DB Chemical Fingerprints. ß-Carotene will react with lipid peroxyl radicals to form a carotenoid radical. There are 5 C40 carotenoids manufactured synthetically on an industrial scale, including lycopene, ss,ss-carotene, and canthaxanthin (which are achiral compounds); zeaxanthin (produced in enantiopure form, as the 3R,3'R enantiomer); and astaxanthin (produced as mixture of configurational … Chemical structures of apo-fucoxanthinoids produced by, Feeding deterrent and toxicity effects of apo-fucoxanthinoids and phycotoxins on a marine copepod (, KEGG Bioinformatics Resource for Plant Genomics and Metabolomics. 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. Unlike brain and macula, peripheral organs such as kidney, liver and lungs accumulate predominant levels of carotenes (beta-carotene and lycopene) [41]. In 2004, 750 carotenoids were compiled by George Britton, Synnφve Liaaen-Jensen and Hanspeter Pfander in the ‘Carotenoids Handbook’ (3). Comparisons with other, conventional fingerprints were done by calculating Tanimoto coefficients of all to all pairs of Carotenoids DB entries. Structural chemical formula and model of chlorophyll B, 2d and 3d illustration, isolated on white background, vector, eps 10 Structural chemical formulas of plant pigments - carotenoids phycobilins - phycocyanobilin, phycourobilin, phycoerythrobilin, 2d illustration, vector, eps8 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. On the other side, the concentration of α- and β-carotene increases in carrots when stored at 2°C and 90% relative humidity, with up to 35% and 25% increases, respectively, after 3 days, and 42%–34% after 10 days of storage [50]. Carotenoids are lipophilic compounds of mainly 40 carbon skeleton synthesized by plants and other organisms (e.g., algae). The carbon-numbering and the naming system follow the Nomenclature of Carotenoids approved by the IUPAC and International Union of Biochemistry (IUB) commissions (11). In terms of carotenoids, eukaryotes seem more closely related to bacteria than to archaea, aside from 16S rRNA lineage analysis. Type Name (acronym) Chemical formula Molecular weight (g/mol) CMC in water (mM) Chemical structure Surface-active ionic liquids ), and cyanobacteria (Synechocystis sp.) Chemically unmodified carotenoids with β end groups can be expected to be provitamin A. Carotenoids with oxygen on both end groups are potentially membrane stabilizers. A generic extraction protocol with the single-stage LC-Orbitrap-MS was developed, enabling the metabolomic screening for carotenoids in tomato fruit tissue [66].

The predominant carotenoids are the provitamin A carotenes, accounting for 75% and 23% of β-carotene and α-carotene, respectively, and 1.9% of lutein. Considering carotenoids, eukaryotes seem more closely related to bacteria than to archaea aside from 16S rRNA lineage analysis. In the course of evolution, carotenoids have been developed to perform diverse functions, probably starting with photosynthetic and photoprotective pigments and later sources of color, odor and taste. Please refer our original paper in detail. Beta Carotene, provitamin A, is an organic red-orange pigment in plants and fruits. We have developed mass spectrometry methods to characterize and measure relative concentrations of products formed by the reaction of β-carotene with free radicals. β-CD: carotenoid oxidative cleavage. Phytoene is the uncolored product, and its desaturation and isomerization result in the synthesis of a red carotenoid, that is, lycopene. Carotenoids can inactivate singlet oxygen by both chemical and physical quenching. 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. Links from the front page of the Carotenoids database are shown in Figure 2. Hydrocarbons (carotenes) and their oxygenated derivatives (xanthophylls) are two main categories of carotenoids. Food composition and physical–chemical characteristics influence the release of carotenoids from food matrix during digestion. New users enjoy 60% OFF. Additionally, the provitamin A activity is the most wide studied property of carotenoids due to severe impact of vitamin A deficiency cause in human body, especially in pregnant women and young children. Sheet of paper in a cage. The unsaturated nature of carotenoids, allow their absorbance at visible range (400–550 nm) and auto-oxidation, which enables scavenging of the ROS [36]. We use Open Babel (http://openbabel.org/wiki/Main_Page) to generate InChI, InChIKey and Canonical SMILES. Based on the facts that β, γ and ε rings are formed from ψ ends, and φ, χ and κ rings are formed from β end groups (1), we can postulate that the carotenogenesis pathways may have evolved dendritically (Table 4). Carotenoids are among the most widely distributed pigments and naturally exhibit red, orange and yellow colors. 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.

Source references are all listed in carotenoid entries and organism entries. However, fishes like salmon and other animals acquire carotenoids through diet. 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. Structural isomers and stereoisomers, such as cis/trans isomers, conformers and enantiomers are extracted by Carotenoid DB Chemical Fingerprints and chemical formula. Chemical names Xylitol C.A.S. Carotenoids are synthesized not only by all photosynthetic organisms but also by some nonphotosynthetic bacteria and fungi. Carotenoids include more than 700 compounds that can be initially divided in carotenes (hydrocarbon carotenoids) and xanthophylls (oxygenated carotenoids) [18]. Carotenoid is a group of pigments naturally present in vegetal raw materials that have biological properties. The general name for a group of fat-soluble pigments found in green, yellow, and leafy vegetables, and yellow fruits. 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’. Carotenoids being the major isoprenoid phytochemicals are synthesized from the five-carbon unit IPP and its isomer DMAPP. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Structures of carotenoids and xanthophylls. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003. Further, enzymatic addition of oxygen to carotenes, results in the formation of a wide range of compounds known as xanthophylls (lutein, zeaxanthin, astaxanthin, fucoxanthin, crocetin, bixin, crocin, beta-cryptoxanthin) and apocarotenoids (retinoic acid, abscisic acid). Only the following solvents may be used for the extraction: methanol, ethanol, propan-2-ol, hexane, acetone, dichloromethane and methyl ethyl ketone. Carotenoids: Physical, Chemical, and Biological Functions and Properties TABLE 3.3 Concentration of Hydrophilic Carotenoids in Water for Almost Complete Inhibition of Aqueous Superoxide Anion (O2• –) Phospholipid 3.15 (Foss et al. In this study, the use of a UHPLC C30 column combining the high chromatographic resolution of UHPLC technology with the single-stage Orbitrap-MS allowed unprecedented and uncompromised separations for carotenoids. Although the numbers of organisms that we have been able to include so far are not evenly distributed in the three domains of life, our statistics on distributions among organisms give some insights into natural history. Carotenoids are a diverse group of pigments that comprise a family of over 700 compounds. Eukaryotes produce only C40 originated carotenoids, including apocarotenoids numbering 154. This introductory chapter addresses the gathering the fundamental knowledge of carotenoids, concerning their nomenclature, structure with stereochemical features, … Carotenoids were extracted using an organic solvent free method. Current Protocols in Food Analytical Chemistry (CPFA), (Supplement 1), F4.3.1 - F 4.3.8 (2001) (John Wiley, New York). α- and β-carotene are geometric isomers and are the principal carotenoids found in carrot, which are considered one of the main sources of carotenoids in diet of the Western countries. Oxygenated carotenoids, as exemplified by lutein and zeaxanthin (Fig. Numbers of unique carotenoids and common carotenoids in the three domains of life. The carotenoids lutein, zeaxanthin, α-carotene, β-carotene, and lycopene (representing both xanthophylls and carotenes) were analyzed. These facts may suggest that the chloroplasts of these primitive unicellular organisms, Cyanidioschyzon merolae, Cyanophora paradoxa and Glaucocystis nostochinearum, may have been derived from the same cyanobacteria which is closely related to Prochlorothrix hollandica in agreement with Takaichi et al. Statistics of Carotenoid DB Chemical Fingerprints are available at ‘http://carotenoiddb.jp/stats/statistics.html’. Natural Eye Health Vitamins with Bilberry Zeaxanthin Lutein - Macular Support Supplement, Formula Based On AREDS2® Clinical Trials Plus Carotenoids Quercetin EGCG - Macutene® Protect (60 Capsules) 4.5 out of 5 stars 119. NinaB: carotenoid oxidative cleavage and Z-E isomerization. Theoretical calculations, their involvement in photosynthesis and in vitro preparation methods (electrochemically, via excited states, by Lewis acids or by oxidation with iodine) are referred to. Carotenoid DB Chemical Fingerprints and conventional fingerprints are downloadable at http://carotenoiddb.jp/FTP/. 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. Total carotenoid content of pomace may be up to 2 g/kg dry matter depending on processing conditions [23]. Beta-carotene, with the molecular formula C40H56, belongs to the group of carotenoids consisting of isoprene units. Synthesized by bacteria, fungi, We have newly developed a tool to search for similar profiled organisms, that helps extracting organisms potentially closely related to any query organism, evolutionarily, or symbiotically, or in food chains. (, Takaichi S.Yokoyama A.Mochimaru M. et al. However, few carotenoids, mainly β-carotene, can be converted in retinol or vitamin A [20]. Carotenoid structures in carrot waste. Animals cannot synthesize carotenoid with few exceptions but take them in their diets as an essential source of retinoids (including vitamin A) (Moran and Jarvik, 2010). 4.13. Food of animal origin contains lower content of carotenoids compared to fruits and vegetables. Singlet oxygen is an excited state of oxygen in which two electrons in the outer orbitals have opposite spin directions. Hydroxylation of the carotene rings produces xanthophylls such as lutein (from α-carotene) and zeaxanthin (from β-carotene). Archaea produce C30 ψ, ψ carotenoids, C40 ψ, ψ carotenoids, β, β carotenoids, β, ε carotenoids, C50 ψ, ψ carotenoids and apocarotenoids. Aiming to extract organisms closely related through the biosynthesis of carotenoids, we developed a precise similarity search system exploiting the ‘Carotenoid DB Chemical Fingerprints’ from the IUPAC semi-systematic names. β-Carotene is also found, achieving 14,600 μg/100 g [25–27]. Two molecules of GGPP are condensed with the help of an important enzyme phytoene synthase (PSY) and result in the production of 40-carbon phytoene. Plants are the only one that can make lutein. All biological functions investigated here are listed at http://carotenoiddb.jp/Biological_activity/biological_activities_list.html. The details are described in Table 1.

Search for other works by this author on: Here we define similarity as reaction likeliness: Carotenoids – Biological Functions and Diversity, Pflanzenfarbstoffe XXV. These position numbers follow the Nomenclature of Carotenoids approved by the IUPAC and IUB commissions (11). Carotenoids are also important bioactive compounds responsible for bright red, yellow and orange hues in many natural matrices. Today, we have an almost-complete picture of the genes and enzymes that catalyze the core reactions of the carotenoid biosynthetic pathway in plants, including Arabidopsis. Carotenoids are widely distributed in the three domains of life according to our current investigations. Related terms: Zeaxanthin; Protein Carotenoids are classified along with their biosynthesis pathways. Several isomeric forms (same formula but different molecular structures) are subsumed under the name. It is an antioxidant that can be found in yellow, orange and … Bendich A (1990) Carotenoids and the immune system. Tomato is widely consumed as raw or processed product (e.g., canned, puree, or sauce) and can provide 85% of dairy lycopene intake. A short overview of naturally occurring carotenoids is presented. I. Its chemical formula is C 40 H 56 O 2. Updated information on the distribution of chemical modification details at phylum level is available at ‘http://carotenoiddb.jp/stats/org_statistics_phylum.html’. Plants are the only one that can make lutein. Mixed carotenoids are obtained by solvent extraction of alfalfa, removal of chlorophylls through saponification and subsequent purification of the carotenoids by solvent extraction. Yisong Guo, ... Madison Davidson, in Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2020. Papaya is an important source of carotenoids due to β-Cryptoxanthin content in the range between 295 and 1034 μg/100 g. Consumption of papaya also provides another advantage related to carotenoid content, due to the elevated content of lycopene, between 1674 and 3674 μg/100 g [31]. 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]. For deeper understanding of the world of carotenoids—how organisms are related via carotenoids, either evolutionarily, or symbiotically, or in food chains through natural histories, and how carotenoids have been evolved with biological functions, we compiled 1117 structures and their distribution among organisms using the latest available original papers. Methods for characterisation include CV, NIR, EPR, ENDOR and resonance Raman spectroscopy. This ‘Search similar profiled organisms’ is available at ‘http://carotenoiddb.jp/search_similar_profiled_organisms.cgi’. Diatoms produce the feeding deterrent apocarotenoids apo-fucoxanthinals and apo-fucoxanthinones against copepods, which may significantly influence food chains (9, 10). Figure 1: The molecular Structure of major carotenoids in human plasma [3] References: Britton, G. (1995). 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. ... Cellular Support Folic Acid Background and Benefits Folic acid has the chemical formula C19H19N7O6 and is known by many other names such as vitamin B9, pteroyl-L … I thank Yasuhiro Tanizawa for advising and helping me to collect original papers. (22). The factual information and practical guidance given in this well received book series ideally complements the informations given in the Handbook. For example, beta-carotene is converted to retinal by beta-carotene-15,15′ oxygenase 1 and 2 and subsequently converted to retinoic acid (vitamin A) by organ specific retinal dehydrogenases [42–45]. The structural differences between these two xanthophylls are the position of the double bond within one of the six-member rings and stereochemistry of one of the hydroxyl (at C-3′) groups (Fig. Reactions of carotenoid dications with suitable nucleophiles are illustrated. We have also investigated a simple method of predicting six biological functions of carotenoids using Carotenoid DB Chemical Fingerprints, which are as provitamin A, membrane stabilizers, odorous substances, allelochemicals, antiproliferative activity and reverse MDR activity against cancer cells. It is considered as an inhibitor of some genes; moreover, it exhibits anticancer and antioxidant properties (Berman et al., 2014… 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.
