Image: Structure of OCP

Light irradiation is a necessary condition for photosynthetic organisms to convert inorganic compounds into organic compounds

"When light is absorbed by carotenoid molecules, OCP can change from an inactive orange to an active red

Scientists have conducted comprehensive research using structural biology, biochemistry, spectroscopy and quantum chemistry methods

The analysis results show that after the photon is absorbed in the OCP, a charge separation reaction may occur between the carotenoid molecule and an amino acid residue of the protein

"Our discovery will allow control of the OCP activation process and its spectral properties
