Introduction Research shows that certain bioactive compounds in our diet have beneficial effects on human health. Among these bioactive molecules, carotenoids are some of the most chemically and functionally diverse molecules in food, which encouraged us to prepare a Special Issue on “Carotenoids and Human Health”. The goal of this Special Issue is to provide a compilation of the recent advances on this important yet understudied research field. This Special Issue contains 11 original research articles, five literature reviews, one communication, and one discussion of cutting edge, peer-reviewed research papers (Figure 1). Figure 1. Topics covered by the Special Issue on carotenoids and human health. Colors present on carotenoids denote structural changes between similar carotenoids. Digital object identifier (DOI), non-alcoholic fatty liver disease (NAFLD), and alcoholic fatty liver disease (AFLD). Carotenoids are a group of pigments produced by all photosynthetic organisms. Due to their broad distribution in nature, it is logical that heterotrophic organisms have adapted and coevolved to utilize carotenoids for their own profit, such it occurs in birds, where the plumage pigmentation is perceived as a “health signal”, conditioning their reproductive success. In humans, some of these compounds serve as vitamin A precursor (pro-vitamin A carotenoids), and others are crucial for

  • The Biosynthesis of Carotenoids
    THE BIOSYNTHESIS OF CAROTENOIDS C. 0. CHICHESTER Department of Food Science and Technology, University of a4fornia, Davis, Galjf 95616, U.S.A. INTRODUCTION Considerable progress has been made in the field of carotenoid bio- chemistry in the last ten to fifteen years. Prior to that very little, if anything, was known about the units which formed the intermediates of the coloured 40—carbon pigments, or the structures of those that were proposed as intermediates. Like all fields of biochemistry, as knowledge is accumulated specific problems are crystallized. These generally concern key areas, which until an understanding is achieved can substantially hinder the unification of a field or problem. The biochemistry of the carotenoids has arrived at this point. INTERMEDIATE COMPOUNDS IN CAROTENOID BIOSYNTHESIS There is general consensus as to the identity of the intermediate com- pounds which form the building blocks of the carotenoids. Studies in Phycornyces blakesleeanus, tomatoes, corn, carrots, Mucor hiemalis, spinach leaves, and bean leaves all coincide to indicate that the common building block of carotenoids is mevalonic acid'—7. Some experiments concerned with carotenoids, and many with sterols, have shown that /3-methyl-/3- hydroxyglutarate-CoA, and/or acetoacetic-CoA, are the normal sources of inevalonic acid" 8 In Phycomyces blalcesleeanus, as well as tomatoes, it has been shown rather unequivocally that the first steps in the conversion of meva- lonic acid to the C—40's are identical to those postulated for the formation of sterols911. The mevalonic acid is converted via the 5-phosphomevalonic acid to the 5-pyrophosphoryl mevalonic acid'2. This compound is then decarboxylated to form the z3-isopentenol pyrophosphate.

ABSTRACT: Maize enriched in provitamin A carotenoids could be key in combatting vitamin A deficiency in human populations relying on maize as a food staple. Consumer studies indicate that orange maize may be regarded as novel and preferred. This study identifies genes of relevance for grain carotenoid concentrations and kernel color, through simultaneous dissection of these traits in 10 families of the U.S. maize nested association mapping population that have yellow to orange grain. Quantitative trait loci (QTL) were identified via joint-linkage analysis, with phenotypic variation explained for individual kernel color QTL ranging from 2.4 to 17.5%. These QTL were cross-analyzed with significant marker-trait associations in a genome-wide association study that utilized ~27 million variants. Nine genes were identified: four encoding activities upstream of the core carotenoid pathway, one at the pathway branchpoint, three within the α- or β-pathway branches, and one encoding a carotenoid cleavage dioxygenase.

  • Inheritance of Beta-Carotene in Tomatoes' Eta
    INHERITANCE OF BETA-CAROTENE IN TOMATOES’ RALPH E. LINCOLW AND JOHN W. PORTERa Purdue Agricdtural Experiment Station, Lafayefte, Indiana Received September 15, 1949 ETA-carotene is the principal vitamin A active carotenoid found in to- B mato fruits. This pigment, however, constitutes only about 5 percent of the total carotenes present in commercial red-fruited varieties. Almost all of the remaining 95 percent of carotene is lycopene. In spite of the relatively small percentage of beta-carotene occurring in red-fruited varieties, tomatoes are classified, nevertheless, as a “good” source of vitamin A for the human diet (HEINZ1942). In 1942 a study aimed at increasing the vitamin content of tomato selections by breeding was initiated at this station. Progress toward the production of varieties genetically constituted to produce high concentrations of provitamin A and ascorbic acid has been reported (LINCOLNet al. 1943, 1949; KOHLERet al. 1947). It also has been reported that selections were made during the course of this work in which beta-carotene constituted 95 percent of the total carotenes (KORLERet al. 1947). This paper reports the results of studies of the inheri- tance of beta-carotene in crosses between high lycopene (low beta-carotene) and high beta-carotene tomato selections. PREVIOUS LITERATURE The results of several studies on the inheritance of tomato flesh and skin color have been summarized by BOSWELL(1937). Most commercial varieties are red fleshed with yellow skin and therefore carry the dominant alleles RTY of yellow flesh (r),tangerine, orange flesh (t) and colorless skin (y). LE ROSEN et al. (1941) have shown that flesh and skin color are genetically and chemically unrelated.

  • Multiplicity of Carotene Patterns Derives from Competition Between
    www.nature.com/scientificreports OPEN Multiplicity of carotene patterns derives from competition between phytoene desaturase diversifcation and biological environments Mathieu Fournié1,2,3 & Gilles Truan1* Phytoene desaturases catalyse from two to six desaturation reactions on phytoene, generating a large diversity of molecules that can then be cyclised and produce, depending on the organism, many diferent carotenoids. We constructed a phylogenetic tree of a subset of phytoene desaturases from the CrtI family for which functional data was available. We expressed in a bacterial system eight codon optimized CrtI enzymes from diferent clades. Analysis of the phytoene desaturation reactions on crude extracts showed that three CrtI enzymes can catalyse up to six desaturations, forming tetradehydrolycopene. Kinetic data generated using a subset of fve purifed enzymes demonstrate the existence of characteristic patterns of desaturated molecules associated with various CrtI clades. The kinetic data was also analysed using a classical Michaelis–Menten kinetic model, showing that variations in the reaction rates and binding constants could explain the various carotene patterns observed. Competition between lycopene cyclase and the phytoene desaturases modifed the distribution between carotene intermediates when expressed in yeast in the context of the full β-carotene production pathway. Our results demonstrate that the desaturation patterns of carotene molecules in various biological environments cannot be fully inferred from phytoene desaturases classifcation but is governed both by evolutionary-linked variations in the desaturation rates and competition between desaturation and cyclisation steps. Carotenoids are organic pigments produced by plants, algae, fungi, and bacteria and can be subdivided into two families of molecules, carotenes and their oxidised counterparts, xanthophylls 1.

Studies have shown that all of the enzymes required for the synthesis of acyclic and cyclic carotenes from mevalonic acid are present in plastids of tomato fruits. Thus, it has been demonstrated that a soluble extract of an acetone powder of tomato fruits converts mevalonic acid to geranylgeranyl pyrophosphate, and isopentenyl pyrophosphate to phytoene, phytofluene, neurosporene and lycopene. Finally, it has been demonstrated that lycopene is converted into mono- and dicyclic carotenes by soluble extracts of plastids of tomato fruits. Whether the enzymes for the conversion of acetyl-CoA to mevalonic acid are also present in tomato fruit plastids has not yet been determined. INTRODUCTION Studies on the enzymatic synthesis of carotenes were, until very recently, plagued by a number of problems. One of these was the fact that the enzymes for the synthesis of carotenes are located in a particulate body, namely chromoplasts or chloroplasts. Hence, a method of solubilization of the enzymes without appreciable loss of enzyme activity was needed. A second problem was concerned with the commercial unavailability of labelled substrate other than mevalonic acid. Thus it became necessary to synthesize other substrates either chemically or enzymatically and then to purify these compounds. Thirdly, the reactions in the synthesis of carotenes appear to proceed much more slowly than many other biochemical reactions.
