Lycopene is an organic compound classified as a tetraterpene and a carotene. Lycopene (from the Neo-Latin Lycopersicon, the name of a former tomato genus)...

which: α-carotene is β,ε-carotene; β-carotene is β,β-carotene; γ-carotene (with one β ring and one uncyclized end that is labelled psi) is β,ψ-carotene; δ-carotene...

δ-Carotene (delta-carotene) or ε,ψ-carotene is a form of carotene with an ε-ring at one end, and the other uncyclized, labelled ψ (psi). It is an intermediate...

{hc}{\Delta E}}} A common example of this phenomenon is in β-carotene.[citation needed] β-carotene (C40H56) is a conjugated polyene with an orange color and...

photosystem II (PSII). These polypeptides bind to chlorophyll a and β-Carotene and pass the excitation energy on to the reaction centre. This family also...

Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and...

the associated predictor X. β is also used in biology, for instance in β-Carotene, a primary source of provitamin A, or the β cells in pancreatic islets...

the two ionization energies. As in benzene, in substances such as beta carotene, chlorophyll, or heme, some electrons in the π orbitals are spread out...

singlet oxygen and protect against its toxic effects. Oxidized products of β-carotene arising from the presence of singlet oxygen act as second messengers that...

photosynthetic membrane. Within the core of the complex, the chlorophyll and beta-carotene pigments are mainly bound to the antenna proteins CP43 (PsbC) and CP47...

green in color and contain the photosynthetic pigment Bchl c as well as γ-carotene. Salt is required for growth. The green sulfur bacteria use a Type I reaction...

pigments such as carotenes and xanthophylls. Algae also use chlorophyll, but various other pigments are present, such as phycocyanin, carotenes, and xanthophylls...
