[4] It is insoluble in water. Lycopene-containing foods are often healthier options in our diet as colorful foods like tomatoes are known to help prevent cancer. An acyclic carotene commonly obtained from tomatoes and other red fruits. Keywords: lycopene intake, bone mineral density, bone resorption, bone formation, oxidative stress. Le lycopène appartient à la famille des caroténoïdes, des pigments naturels qui donnent leur couleur jaune-orange (carotènes) et rouge (lycopène) aux végétaux et à certains animaux. The quenching mechanism of singlet oxygen by lycopene is analyzed based on the calculations at the B3LYP/6-311+(d,p) level. Lycopene is fat-soluble, so the oil is said to help absorption. Lycopene is a lipid-soluble carotenoid that exists in both all-trans and cis-configurations in nature. March 26, 2016. Density functional theory has been applied to optimize the configurations of the ground and excited states of lycopene and oxygen respectively. [33] The US Food and Drug Administration (FDA), in rejecting manufacturers' requests in 2005 to allow "qualified labeling" for lycopene and the reduction of various cancer risks, provided a conclusion that remains in effect as of 2017[update]: "...no studies provided information about whether lycopene intake may reduce the risk of any of the specific forms of cancer. Lycopene is a key intermediate in the biosynthesis of carotenoids, such as beta-carotene, and xanthophylls. Plasma antioxidants and cognitive performance in middle-aged … What is Lycopene. Lipids.

The median and 99th percentile of dietary lycopene intake have been estimated to be 5.2 and 123 mg/d, respectively. [4] Lycopene dietary supplements (in oil) may be more efficiently absorbed than lycopene from food. Serum lycopene level changes with dietary lycopene intake irrespective of the amount of fat intake. ; Tomato lycopene and low-density lipoprotein oxidation: a human dietary intervention study. Current studies show that lycopene holds antioxidant properties. Lycopene and myocardial infarction risk in the EURAMIC study. [14] The discoloration is expected to fade after discontinuing excessive lycopene intake. Lycopene is a naturally occurring red pigment, which belongs to the family of carotenoids. Moderate intervention with carotenoid-rich vegetable products reduces lipid peroxidation in men. 2000; 130:2200-2206. Lycopene extraction from tomatoes, as a promising health-promoting functional food ingredient, is drawing increasing attention by the food industry. A powerful antioxidant that prevents free radicals that can damage cells. In recent epidemiological studies, tissue and serum levels of lycopene, a carotenoid available from tomatoes, have been found to be inversely related to risk of coronary heart disease. The carotenoid standard (lycopene) prepared was kept in a screw cap small dark bottle (2 mL) and refrigerated at 4ºC until used. [4] Although gac (Momordica cochinchinensis Spreng) has the highest content of lycopene of any known fruit or vegetable (multiple times more than tomatoes),[17][18] tomatoes and tomato-based sauces, juices, and ketchup account for more than 85% of the dietary intake of lycopene for most people. Mordente, A, et al. Our previous studies showed that in vitro enrichment of low-density lipoprotein (LDL) with β-carotene protected it from cell-mediated oxidation. Stage 1 hypertensive subjects. [3][24] Some foods that do not appear red also contain lycopene, e.g., asparagus, which contains about 30 μg of lycopene per 100-g serving[3] (0.3 μg/g) and dried parsley and basil, which contain around 3.5–7.0 μg/g of lycopene. 49. Effect of lycopene on the copper-induced oxidation of low-density lipoprotein in broiler chickens.

Lycopene absorbs all but the longest wavelengths of visible light, so it appears red. Lycopene is also found to concentrate in the adrenal, liver, testes, and prostate. Lycopene is the pigment in tomato sauces that turns plastic cookware orange. It is a member of the carotenoid family of compounds, and because it consists entirely of carbon and hydrogen, is also a carotene. RESULTS: The lipid profile showed lycopene and astaxanthin decreased total cholesterol, low-density lipoprotein-cholesterol (LDL-C), very LDL-C, and triglycerides and increased high-density lipoprotein-cholesterol level significantly (P < 0.05) compared to the control but less than atorvastatin. 1998; 33:981-984. If not diluted the amount of lycopene in the assay may be too high, leading to either incomplete extraction or too high of an absorbance value. 1997;146(8):618-626.9345115. Formulated products containing more than just tomatoes can also be analyzed using this procedure but only with care. Different isomers were shown to have different stabilities due to their molecular energy (highest stability: 5-cis ≥ all-trans ≥ 9-cis ≥ 13-cis > 15-cis > 7-cis > 11-cis: lowest). [11] Efficient energy transfer occurs between the encapsulated dye and nanotube — light is absorbed by the dye and without significant loss is transferred to the nanotube. Lycopene travels to the extrahepatic organs through the systemic blood and is available there for its biological action. [19], Unlike other fruits and vegetables, where nutritional content such as vitamin C is diminished upon cooking, processing of tomatoes increases the concentration of bioavailable lycopene. Kyung-Woo Lee, Won-Don Choo, Chang-Won Kang and Byoung-Ki AnEmail author Lipids (1998): 981-984. [4], In plants, algae, and other photosynthetic organisms, lycopene is an intermediate in the biosynthesis of many carotenoids, including beta-carotene, which is responsible for yellow, orange, or red pigmentation, photosynthesis, and photoprotection. Lycopene is a pigment that gives many fruits and vegetables their red colour. Full Text PDF [647K] Abstracts References(38) Cited-By(2) Intake of the antioxidant lycopene has been reported to decrease oxidative stress and have beneficial effects on bone health. Lycopene is a compound or a pigment which gives red color to fruits and vegetables such as tomatoes, watermelon, pink grapefruit and guava. Lycopene (from the neo-Latin Lycopersicum, the tomato species) is a bright red carotenoid hydrocarbon found in tomatoes and other red fruits and vegetables, such as red carrots, watermelons, grapefruits, and papayas, but it is not present in strawberries or cherries. La recherche elle-même n'ayant pas été publiée, d'autres chercheurs travaillant sur les anti-oxydants ne sont pas convaincus par cet argument. Khachik F, Beecher GR, … The bleach oxidizes the lycopene, thus allowing the now-polarized metabolite to dissolve. Clin Nephrol 1999;52(1):30-36. Research suggests that increased lycopene intake may reduce the risk of lung cancer. Carotenoids may protect low-density lipoprotein from oxidation, a process implicated in the development of atherosclerosis. Based on the above, FDA concludes that there is no credible evidence supporting a relationship between lycopene consumption, either as a food ingredient, a component of food, or as a dietary supplement, and any of these cancers. Compare Products: Select up to 4 products. Current studies show that lycopene holds antioxidant properties. Eleven conjugated double bonds give lycopene its deep red color. ↑ Bub A, Watzl B, Abrahamse L, et al. J Nutr. Human monocyte-derived macrophages (HMDM) were incubated with lycopene in the presence or absence of native LDL (nLDL) or LDL modified by oxidation (oxLDL), aggregation (aggLDL), or acetylation (acLDL). Owing to the strong color, lycopene is useful as a food coloring (registered as E160d) and is approved for use in the USA,[5] Australia and New Zealand (registered as 160d)[6] and the European Union. Lipids. [10], Dispersed lycopene molecules can be encapsulated into carbon nanotubes enhancing their optical properties. Il existe également des preuves de l'action du lycopène sur la réduction de l'oxydation des LDL (low-density lipoprotein = lipoprot� References. Rousseau EJ, Davison AJ, Dunn B. However, a diet high in olive oil and rich in lycopene may decrease the risk of coronary heart disease by improving the serum lipid profile compared with a high-carbohydrate, low-fat, lycopene-rich di … [4] Synthesis begins with mevalonic acid, which is converted into dimethylallyl pyrophosphate. Laboratory of Poultry Nutrition, Department of Animal Science and Technology, College of Animal Bioscience and Technology, Konkuk University. Lycopene has antioxidant property. Lycopene bioavailability (absorption) can be influenced by many factors. In the present work, the effect of lycopene on copper induced oxidation of isolated low‐density lipoprotein (LDL) and the related mechanism were investigated. [12], The unconditioned biosynthesis of lycopene in eukaryotic plants and in prokaryotic cyanobacteria is similar, as are the enzymes involved. Lycopene diet reduces the risk of developing a number of chronic diseases, both the cardiovascular system and internal organs. Lycopene and its cis isomers were analysed by HPLC with photodiode array detection. Because of its lipophilic nature, lycopene concentrates in low-density and very-low-density lipoprotein fractions of the serum. Lycopene is packaged in very low-density lipoproteins (VLDL) and high-density lipoproteins (HDL) by the liver and released to the systemic circulation (6). RESULTS: The lipid profile showed lycopene and astaxanthin decreased total cholesterol, low-density lipoprotein-cholesterol (LDL-C), very LDL-C, and triglycerides and increased high-density lipoprotein-cholesterol level significantly (P < 0.05) compared to the control but less than atorvastatin. Moderate intervention with carotenoid-rich vegetable products reduces lipid peroxidation in men. In this respect, skin lycopene has been reported to be more sensitive to UV light stress than b-carotene. Lycopene standard was heated at 50, 100 and 150 C or illuminated at 25 C for varied lengths of time. The two terminal isoprene groups of lycopene can be cyclized to produce beta-carotene, which can then be transformed into a wide variety of xanthophylls.[4]. 15-cis-phytoene + 4 an oxidized electron acceptor -> all-trans-lycopene + 4 a reduced electron acceptor, 15-cis-phytoene + 5 an oxidized electron acceptor -> all-trans-3,4-didehydrolycopene + 5 a reduced electron acceptor, all-trans-zeta-carotene + 2 an oxidized electron acceptor -> all-trans-lycopene + 2 a reduced electron acceptor, trans-lycopene biosynthesis II (oxygenic phototrophs and green sulfur bacteria), all-trans neurosporene + an oxidized electron acceptor -> all-trans-lycopene + a reduced electron acceptor, all-trans-lycopene + 2 oxygen -> 2 sulcatone + bixin aldehyde, all-trans-lycopene + 2 oxygen -> 4,9,13-trimethyltetradeca-2,4,6,8,10,12-hexaene-1,14-dial + pseudoionone + geranial, all-trans-lycopene + 2 oxygen -> 4,9-dimethyldodeca-2,4,6,8,10-pentaene-1,12-dial + 2 pseudoionone, all-trans-lycopene + 2 oxygen -> bixin aldehyde + 2 sulcatone, all-trans-lycopene + 2 oxygen -> pseudoionone + 4,8,13-trimethylhexadeca-heptaenedial + sulcatone, all-trans-lycopene + an oxidized electron acceptor -> all-trans-3,4-didehydrolycopene + a reduced electron acceptor.
