*WHAT ARE NITRATES?Nitrates (NO3) are compounds composed of a nitrogen and three oxygen atoms and are often the final stage in the nitrogen cycle of fresh and saltwater aquariums if there are not nitrate removing plants, algae, or nitrate reducing anaerobic bacteria present. Nitrates are the ...
The more nitrogen atoms are in the bridge chain, the greater its contribution to the enthalpy of formation. Second, the oxidation state of nitrogen atoms in the bridge significantly affects the energy of the bridge. The maximum contribution is made by the azo bridge (entry 5); both its ...
Many important structural and mechanistic aspects of the antiport mechanism remain elusive: (1) Can antiporters be distinguished from other transporters (uniporters and symporters) based on their protein architecture and conformational transition mechanism? (2) How is the empty transporter prevented from...
