Deep eutectic solvents (DESs) are emerging as a new class of green solvents with the potential to replace organic solvents in many applications both at industrial and academic level. In this work, the authors offer an unprecedented characterization of the behavior of the bacterial photosynthetic reaction center (RC) from Rhodobacter sphaeroides in a series of choline-based DESs. RC is a membrane-spanning three-subunit pigment-protein complex that, upon illumination, is capable to produce a stable charge-separated state. Thus, it represents the ideal model for carrying out basic studies of protein-solvent interactions. Herein, the authors first report that, in many DES mixtures investigated, RC (a) is stable, (b) is capable to generate the charge-separated state, and (c) even to perform its natural photocycle. It proved, indeed, to be effective in reducing quinone mols. to quinol by withdrawing electrons from cyto-chrome c. As an example of biotechnol. application, a photoelectrochem. cell based on DES-dissolved RC has also been designed and successfully employed to generate photocurrents arising from the reduction of the electron-donor ferrocenemethanol. In the experiment, the researchers used many compounds, for example, 2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7Product Details of 605-94-7).
2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Product Details of 605-94-7
