1998; 33:981-984. Incompatible with strong oxidizing agents. [26] Because lycopene may cause low blood pressure, interactions with drugs that affect blood pressure may occur. Stage 1 hypertensive subjects. [25], Lycopene is non-toxic and commonly found in the diet, mainly from tomato products. 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. J Nutr. Kohlmeier I, Kark JD, Gomez-Gracia E, et al. Le lycopène et le bêta-carotène étant très semblables, ceci laisse donc entendre que le lycopène est nocif. Lipids. Lycopene extraction from tomatoes, as a promising health-promoting functional food ingredient, is drawing increasing attention by the food industry. Gac has high lycopene content derived mainly from its seed coats. This is then condensed with three molecules of isopentenyl pyrophosphate (an isomer of dimethylallyl pyrophosphate), to give the 20-carbon geranylgeranyl pyrophosphate. Lycopene is a compound or a pigment which gives red color to fruits and vegetables such as tomatoes, watermelon, pink grapefruit and guava. Plasma antioxidants and cognitive performance in middle-aged … [3], In humans, the Observed Safe Level for lycopene is 75 mg/day, according to one preliminary study. Lycopene is a lipid-soluble carotenoid that exists in both all-trans and cis-configurations in nature. Lycopene can deeply remove vascular waste, regulate plasma cholesterol concentration, protect low-density lipoprotein (LDL) from oxidation, repair and perfect oxidized cells, promote intercellular glial formation, and enhance vascular flexibility. CC(=CCC/C(=C/C=C/C(=C/C=C/C(=C/C=C/C=C(/C=C/C=C(/C=C/C=C(/CCC=C(C)C)\C)\C)\C)/C)/C)/C)C [4] When exposed to light or heat, lycopene can undergo isomerization to any of a number of cis-isomers, which have a bent rather than linear shape. 1998; 33:981-984. References. Compare Products: Select up to 4 products. 49. 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). acentric factor. ↑ Erdman JW Jr, Ford NA, Lindshield BL.

Several human epidemiological studies, supplemented by in vivo and in vitro studies, have shown decreased bone loss following the consumption of lycopene/tomato. An Optical Density (OD) of 1 = 3.1206 µg of lycopene per mL. Lycopene bioavailability in processed tomato products is higher than in unprocessed fresh tomatoes. CopyCopied, OAIJSZIZWZSQBC-GYZMGTAESA-N [21] Processed tomato products such as pasteurized tomato juice, soup, sauce, and ketchup contain a higher concentration of bioavailable lycopene compared to raw tomatoes. Formula for lycopene content: For preparation of standard lycopene , 1 mg of lycopene (Sigma,USA) standard was separately dissolved in 1 mL of absolute HPLC grade chloroform (Sigma, Germany). Moderate intervention with carotenoid-rich vegetable products reduces lipid peroxidation in men. Lycopene standard was heated at 50, 100 and 150 C or illuminated at 25 C for varied lengths of time. [4] It is insoluble in water. Increase in low density lipoprotein (LDL) oxidation is hypothesized to be causally associated with increasing risk of atherosclerosis and coronary heart disease. The supercritical fluid process is being … Search results for lycopene at Sigma-Aldrich. 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. Tomato lycopene and β-carotene inhibit low density lipoprotein oxidation and this effect depends on the lipoprotein vitamin E content Two molecules of this product are then condensed in a tail-to-tail configuration to give the 40-carbon phytoene, the first committed step in carotenoid biosynthesis. ; Tomato lycopene and low-density lipoprotein oxidation: a human dietary intervention study. Abstract The molecular structural and Raman spectroscopic characteristics of β‐carotene and lycopene are investigated by density functional calculations. Available research suggests that doses of more than 25 milligrams of lycopene daily may lower levels of low-density lipoprotein (LDL, or “bad”) cholesterol and total cholesterol. High lycopene foods include guavas, cooked tomatoes, watermelon, grapefruit, papaya, sweet red peppers, persimmon, asparagus, red cabbage, and mangos. 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. Lycopene is especially interesting because of its considerable antioxidant activity that highly exceeds that of b-carotene and a-tocopherol [7,8]. Encapsulation increases chemical and thermal stability of lycopene molecules; it also allows their isolation and individual characterization. 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). In animal models of atherosclerosis, lycopene and tomato products decreased plasma total cholesterol, LDL cholesterol and increased high-density lipoprotein cholesterol. To remove this staining, the plastics may be soaked in a solution containing a small amount of chlorine bleach. 48. MF: C40H56, MW: 536.87. Heat sensitive - store at -70 C. Combustible. Research suggests that increased lycopene intake may reduce the risk of lung cancer. The bleach oxidizes the lycopene, thus allowing the now-polarized metabolite to dissolve. ↑ Bub A, Watzl B, Abrahamse L, et al. Experimental Density: 350.7 g/mL Biosynth Q-100561: Miscellaneous. Lycopene may affect the immune system, the nervous system, sensitivity to sunlight, or drugs used for stomach ailments. Kyung-Woo Lee, Won-Don Choo, Chang-Won Kang and Byoung-Ki AnEmail author 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]. Meta-analysis on serum lipids revealed a significant cholesterol-lowering effect of lycopene for total serum cholesterol (mean change±SE: -7.55±6.15mg/dl; p=0.02) and low-density-lipoprotein (LDL) cholesterol (mean change±SE: -10.35±5.64mg/dl, p=0.0003) in the subgroup of trials using lycopene dosages of ≥25mg daily, whereas subgroup meta-analysis of trials using lower lycopene dosages was … Several human epidemiological studies, supplemented by in vivo and in vitro studies, have shown decreased bone loss following the consumption of lycopene/tomato. Kyung-Woo Lee, Won-Don Choo, Chang-Won Kang and Byoung-Ki AnEmail author [8] In human blood, various cis-isomers constitute more than 60% of the total lycopene concentration, but the biological effects of individual isomers have not been investigated. Lycopene is a lipid-soluble carotenoid that exists in both all-trans and cis-configurations in nature. Carotenoids may protect low-density lipoprotein from oxidation, a process implicated in the development of atherosclerosis. 2000; 130:2200-2206. [4] Ketchup is a common dietary source of lycopene. Lycopene travels to the extrahepatic organs through the systemic blood and is available there for its biological action. J Nutr. [14] The discoloration is expected to fade after discontinuing excessive lycopene intake. The quenching mechanism of singlet oxygen by lycopene is analyzed based on the calculations at the B3LYP/6-311+(d,p) level. Tomato and tomato products are rich sources of lycopene. Lycopene is packaged in very low-density lipoproteins (VLDL) and high-density lipoproteins (HDL) by the liver and released to the systemic circulation (6). An acyclic carotene commonly obtained from tomatoes and other red fruits. Free radical scavenging properties of Lycopene (LYC), Phytofluene (PF), and Phytoene (PE) are studied experimentally, considering the electron transfer mechanism and using the ABTS•+ decolouration assay. [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. [4] The lycopene content of tomatoes depends on variety and increases as the fruit ripens. Because of its lipophilic nature, lycopene concentrates in low-density and very-low-density lipoprotein fractions of the serum. Tomato and tomato products are rich sources of lycopene. [4] Intestinal absorption of lycopene is enhanced by the presence of fat and by cooking. Lycopene, a carotenoid found in tomato products, prevents oxidation of low density lipoprotein (LDL) cholesterol and reduces the risk of developing atherosclerosis and coronary heart disease according to a recent study published in the October 1998 issue of Lipids (Agarwal, S., and Rao A.V. Incompatible with strong oxidizing agents. Lycopene may protect against cardiovascular disease by decreasing cholesterol synthesis and increasing the degradation of low-density lipoproteins. [9], Carotenoids like lycopene are found in photosynthetic pigment-protein complexes in plants, photosynthetic bacteria, fungi, and algae. Lycopene is fat-soluble, so the oil is said to help absorption. Curr Med Chem. [4][20] Lycopene in tomato paste is up to four times more bioavailable than in fresh tomatoes.

Studies show that lycopene intake is significantly associated with lower risk of lung, colon and stomach carcinogenesis. Increase in low density lipoprotein (LDL) oxidation is hypothesized to be causally associated with increasing risk of atherosclerosis and coronary heart disease. Lycopene bioavailability (absorption) can be influenced by many factors. Moderate intervention with carotenoid-rich vegetable products reduces lipid peroxidation in men. Il existe également des preuves de l'action du lycopène sur la réduction de l'oxydation des LDL (low-density lipoprotein = lipoprot� [23] Cara cara navel, and other citrus fruit, such as pink grapefruit, also contain lycopene. Insoluble dans l’eau, le lycopène est transporté par les lipides du sang et s’accumule dans certains organes, en particulier dans le foie et la prostate. Lycopene travels to the extrahepatic organs through the systemic blood and is available there for its biological action. Two different mean particle sizes (80 and 345 μm) were used at two solvent flow rates (0.792 and 1.35 kg/h). Lycopene is a naturally occurring red pigment, which belongs to the family of carotenoids. Lycopene absorbs all but the longest wavelengths of visible light, so it appears red. 2000; 130:2200-2206. Lycopene (molecular formula: C40H56) is a linear, unsaturated hydrocarbon carotenoid, the major bright red pigment, a phytochemical found in fruits such as tomatoes and other red fruits such as papaya, pink grapefruit, apricots, red oranges, watermelon, rosehips and guavas 3).Lycopene is the most common carotenoid in the human body and is one of the most potent … In its natural, all-trans form, the molecule is long and straight, constrained by its system of 11 conjugated double bonds. [4] They are responsible for the bright orange–red colors of fruits and vegetables, perform various functions in photosynthesis, and protect photosynthetic organisms from excessive light damage. Formulated products containing more than just tomatoes can also be analyzed using this procedure but only with care. Lycopene is a lipid-soluble carotenoid that exists in both all-trans and cis-configurations in nature. Lycopene is not an essential nutrient for humans, but is commonly found in the diet mainly from dishes prepared from tomatoes. Lycopene may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by a liquid chromatography technique. [33][dead link] A 2020 review of randomized control trials found conflicting findings for lycopene improving cardiovascular risk factors. The carotenoid standard (lycopene) prepared was kept in a screw cap small dark bottle (2 mL) and refrigerated at 4ºC until used. Schmidt R, Hayn M, Reinhart B, et al. 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. [26], Lycopenemia is an orange discoloration of the skin that is observed with high intakes of lycopene. 48. 13: 407-433 (1992). 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. Mordente, A, et al. Stability: Heat sensitive - store at -70 C. Combustible. The bioavailability of cis-isomers in food is higher than that of all-trans isomers. 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. The extraction process is a unit operation used to obtain targeted food components from natural products such as lycopene from tomatoes. 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. It is found in tomatoes, watermelon and papaya. Lycopene is packaged in very low-density lipoproteins (VLDL) and high-density lipoproteins (HDL) by the liver and released to the systemic circulation (6). Effect of lycopene on the copper-induced oxidation of low-density lipoprotein in broiler chickens. Lycopene, CAS: 502-65-8, is a highly conjugated antioxidant carotenoid compound. 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. Although this is promising, more high-quality research is needed in this area. However, in vitro enrichment with either lutein or lycopene actually enhanced oxidation of the LDL. [4] Like all carotenoids, lycopene is a tetraterpene. 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. ↑ Erdman JW Jr, Ford NA, Lindshield BL. Formulated products containing more than just tomatoes can also be analyzed using this procedure but only with care. Tomato lycopene and low density lipoprotein oxidation: a human dietary intervention study. [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. Effect of lycopene on the copper-induced oxidation of low-density lipoprotein in broiler chickens. 48. Lycopene is the pigment in tomato sauces that turns plastic cookware orange. The dual wavelength procedure should be used and the density of the material checked if the sample is to be added by volume. Additional lycopene benefits are that it also reduces low density lipoprotein (LDL) oxidation and reduces cholestoral levels in the blood. Lycopene diet reduces the risk of developing a number of chronic diseases, both the cardiovascular system and internal organs. [26] Lycopene may increase the risk of bleeding when taken with anticoagulant drugs. Lycopene and myocardial infarction risk in the EURAMIC study. molar density of solvent. [7], Lycopene is a symmetrical tetraterpene assembled from eight isoprene units. Lycopene is also found to concentrate in the adrenal, liver, testes, and prostate. Tomato lycopene and low density lipoprotein oxidation: a human di- etary intervention study. Lycopene is a pigment that gives many fruits and vegetables their red colour. Through several desaturation steps, phytoene is converted into lycopene. Lycopène : caractéristiques. [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. Lycopene and its cis isomers were analysed by HPLC with photodiode array detection.

Several human epidemiological studies, supplemented by in vivo and in vitro studies, have shown decreased bone loss following the consumption of lycopene/tomato. Tomato lycopene and low density lipoprotein oxidation: a human di- etary intervention study. A powerful antioxidant that prevents free radicals that can damage cells. The median and 99th percentile of dietary lycopene intake have been estimated to be 5.2 and 123 mg/d, respectively. [27] A 2010 review concluded that research has been insufficient to establish whether lycopene consumption affects human health. [3][4] The median and 99th percentile of dietary lycopene intake have been estimated to be 5.2 and 123 mg/d, respectively. It is insoluble in plain water, but it can be dissolved in organic solvents and oils. Because of its non-polarity, lycopene in food preparations will stain any sufficiently porous material, including most plastics. Although lycopene from tomatoes has been tested in humans for cardiovascular diseases and prostate cancer, no effect on any disease was found. ↑ Bub A, Watzl B, Abrahamse L, et al. 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).

Lycopene (molecular formula: C40H56) is a linear, unsaturated hydrocarbon carotenoid, the major bright red pigment, a phytochemical found in fruits such as tomatoes and other red fruits such as papaya, pink grapefruit, apricots, red oranges, watermelon, rosehips and guavas 3).Lycopene is the most common carotenoid in the human body and is one of the most potent … Lipids. 1. Laboratory of Poultry Nutrition, Department of Animal Science and Technology, College of Animal Bioscience and Technology, Konkuk University. [4] Isolation procedures for lycopene were first reported in 1910, and the structure of the molecule was determined by 1931. Our previous studies showed that in vitro enrichment of low-density lipoprotein (LDL) with β-carotene protected it from cell-mediated oxidation. Tomato and tomato products are rich sources of lycopene. The effect of lycopene on macrophage foam cell formation induced by modified low-density lipoprotein (LDL) was studied. Quantitative growth experiments conducted in dark, semiaerobic conditions, using a growth medium for high cell density and high intracellular membrane levels, which are suitable for the conventional industrial production in the absence of light, yielded lycopene at up to 2 mg/g (dry weight) of cells or up to 15 mg/liter of culture. [3] Although lycopene is chemically a carotene, it has no vitamin A activity. Lycopene is a compound or a pigment which gives red color to fruits and vegetables such as tomatoes, watermelon, pink grapefruit and guava. Rousseau EJ, Davison AJ, Dunn B. [4] Lycopene dietary supplements (in oil) may be more efficiently absorbed than lycopene from food. Lycopene-containing foods are often healthier options in our diet as colorful foods like tomatoes are known to help prevent cancer. Density functional theory has been applied to optimize the configurations of the ground and excited states of lycopene and oxygen respectively. [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. The effect of lycopene on macrophage foam cell formation induced by modified low-density lipoprotein (LDL) was studied. Lipids. There are cases of intolerance or allergic reaction to dietary lycopene, which may cause diarrhea, nausea, stomach pain or cramps, gas, and loss of appetite. In early 2009, one study found 10 milligrams of lyocpene per day helps maintain bone density compared to taking only 3 milligrams per day (8) while another study in the same month found 12 milligrams of lycopene per day to be superior to 4 milligrams per day for bone health (9). [14], A 2017 review concluded that tomato products and lycopene supplementation had small positive effects on cardiovascular risk factors, such as elevated blood lipids and blood pressure.
