DNA where the emphasis is not on the bonding - students think that it is a full bond with a hydrogen. Students may have not met the orbital model of the atoms when they first meet hydrogen bond - ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...

The scientists used WW domain, a protein domain with two conserved tryptophan residues, to model the folding process. Using data from MD simulations of the protein domain folding and unfolding, they ...

To do this, the scientists used a model system consisting of a perylenediimide chromophore and a nitroxide radical that self-assembles into functional units in solution by means of hydrogen bonds.
