WebJul 4, 2024 · This means the molecule can now rotate around this single bond, which it does by swiveling through 180 o. The double bond then reforms and locks the molecule back into position in a trans configuration of the all-trans-retinal. This isomerization occurs in a few picoseconds (10-12 s) or less. WebSep 21, 2024 · Carotenoids are alkene molecules that contain π-electron conjugated bonds, and have many functions in organic life, such as energy transfer, photoprotection and interception of singlet oxygen [11,12,13]. Carotenoids interacting with chlorophyll in the singlet state which will lead to a quenching of chlorophyll fluorescence.
