Chlorophyll chromophor
WebThe chlorophyll molecule transfers the excited electron from the first singlet state to an electron acceptor and a pos-the excited electron is bound less strongly to the chromophore molecule than in the ground state. When the chlorophyll molecule returns to the ground state, the free energy derived from this process is conserved for chemical work. WebA list of some simple chromophores and their light absorption characteristics is provided on the left above. The oxygen non-bonding electrons in alcohols and ethers do not give rise to absorption above 160 nm. Consequently, pure alcohol and ether solvents may be used for spectroscopic studies.

WebThe chromophore is an open chain tetrapyrrole, known as phytochromobilin (?ϕβ), and is attached to the apoprotein at a conserved cysteine residue ( Fig. 26-7B ). The ?ϕβ chromophore is similar in structure to phycocyanobilin (PCB), which is the chromophore in blue-green algae.
