Plastoquinone
Plastoquinone is a lipid-soluble, electron-transport molecule found in the chloroplasts of plants and algae, as well as in some bacteria. It plays a crucial role in the light-dependent reactions of photosynthesis, specifically within the thylakoid membranes of the chloroplasts. Structurally, plastoquinone is a quinone, a type of organic compound that contains two ketone groups adjacent to each other.
During the light-dependent reactions of photosynthesis, plastoquinone facilitates the transfer of electrons from Photosystem II (PSII)
Plastoquinone exists in two main forms: oxidized (plastoquinone, PQ) and reduced (plastoquinol, PQH2). The oxidized form
The importance of plastoquinone extends beyond its role in electron transport. It also participates in the
