Aside from tomatoes or tomato products like ketchup, it is found in watermelons, grapefruits, red guavas, and baked beans. [4] It has no vitamin A activity. [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 ...
To date, no X-ray crystal structure of lycopene has been reported. UV spectra of lycopene in hexane. A typical carotenoid, lycopene displays three absorbance maxima. A peak at 360 nm would indicate the presence of certain cis-isomers
This is reinforced by the widespread consumption of “pickled green” and “fried green tomatoes” and the consumption of high-tomatine tomatoes (a variant of L. esculentum var. cerasiforme, better known as the "cherry tomato", indigenous to Peru) with very high tomatine content (in the range of 500–5000 μg/kg of dry weight). [25]
This again introduces two double bonds, resulting in 7,9,7’,9’-tetra-cis-lycopene. CRTISO, a carotenoid isomerase, is needed to convert the cis-lycopene into an all-trans lycopene in the presence of reduced FAD. This all-trans lycopene is cyclized; cyclization gives rise to carotenoid diversity, which can be distinguished based on the end ...
Lycopenemia is a harmless skin condition caused by excessive ingestion of red foods containing lycopene, such as tomatoes, red cabbage, chili beans, and various fruits and berries, which leads to a reddish discoloration of the skin. [1]: 486

In 2000 it was discovered that the gene insertion of a bacterial phytoene desaturase into transgenic tomatoes increased the lycopene content without the need to alter several of the plants enzymes. [5] This approach was later used in rice to increase its β-carotene content resulting in the Golden Rice project.
orange pigments . α-Carotene – to vitamin A carrots, pumpkins, maize, tangerine, orange.; β-Carotene – to vitamin A dark, leafy greens, red, orange and yellow fruits and vegetables.
