Lycopene bent rather than linear shape. 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). 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. Carotenoids like lycopene are found in photosynthetic pigment-protein complexes in plants, photosynthetic bacteria, fungi, and algae. 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.
Lycopene food, or as a dietary supplement, and any of these cancers." 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. A 2010 review concluded that research has been insufficient to establish whether lycopene consumption affects human health. Lycopene has been studied in basic and clinical research for its potential effects on cardiovascular diseases and prostate cancer, although results through 2017 have not changed the prevailing FDA view that evidence of benefit remains inconclusive. Lycopene Lycopene (from the neo-Latin "Lycopersicum", the tomato species) is
