Hydrogen bonds are quite small, on the level of a few angstroms. They can also be passed between two different molecules ... . But in spite of these properties, researchers have recently observed hydrogen-bond exchange taking place in real ...
... posted on A Blog Around the Clock a few days ago discusses the mechanisms behind hydrogen bonding. The first half of the video is visually ...
... channels. The water molecules travel in chains - because they interact with each other strongly via hydrogen bonds. "You can visualize it as mini-freight ...
... the folding process, such as breaking protein-water-hydrogen bonds and replacing them with protein-protein ... , Gruebele said. The remaking of hydrogen bonds helps organize the structure of a protein. In tests on ubiquitin, a common ...
... makes the molecule so unusual is its two hydrogen bonds, which are similar to those found in water. Chemists know ... , it may have broader ramifications to biological systems that depend on hydrogen bonds," he says. The breakthrough was enabled by laser ...
... in the membrane. "As the transporter, with all these arginine guanidinium groups, approaches the cell, it basically does a handshake using hydrogen bonds with cell surface constituents that are in the membrane ...
... a nanosecond or less. Their latest experiments center on the hydrogen bonding that makes the sugars rigid. They have shown ... more convenient than using neutrons and could be used for routine formulation evaluation. Hydrogen bonds are responsible for many of water’s properties; they make ...
... TATB, are bound together by a strong network of hydrogen-bonds. This extended network often makes ... fluoride anions that are highly effective in dissolving hydrogen-bonded materials such as TATB. (An anion is an atom ...

Hydroxide ions form extra hydrogen bond to speed through water
Water`s unrivaled omnipresence and the crucial role it plays in life drives scientists` to understand every detail of its unusual underlying properties on the microscopic scale.
... , gas, wood or other organic materials uses molecular oxygen, the O2 we breathe, to break carbon-hydrogen bonds and release energy. This reaction, better ...
