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.
Through colour render of Practice by the manufacturing companies listed below; Through colour render Through colour render is a sand/cement/lime based render that is made from White Portland cement (WOPC) and added pigment to produce a coloured effect that is throughout the body of the material. The pigment is preblended into the product as part of the manufacturing process to produce a prebagged product. Another name for these type of materials is monocouche renders. Various mix designs can be produced in renders according to the published Code of Practice for External Renderings, BS5262 1991. The through colour render market within Europe produces a
