Hydrogen bonds are key constituents of biomolecular structures, and their response to external perturbations may reveal important insights about the most stable components of a structure. NMR ...

Nobel Laureate Linus Pauling, Ph.D., predicted in 1939 that hydrogen bonding would prove to be more significant in the field of biology than any other type of chemical bond. His prediction has been ...

Researchers at the University of California, Santa Barbara have shown that, under the right circumstances, hydrogen can form multicenter bonds, where one hydrogen atom simultaneously bonds to as many ...

Hydrogen bonds are at the very core of life as we know it, and now for the first time ever scientists have managed to visualize these transient molecular associations. This technique can be used to ...

As with magnets and alternating current, positively charged molecules never aim for one another. Indeed, similarly charged poles are repelled. Nevertheless, scientists have managed to bond positively ...

The latest short science news items from C&EN. Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA ...

Proteins are made of amino acid chains, or polypeptides. Amino acids have a basic backbone made of an amino group and a carboxyl group, and differ in their side-chains. These polypeptide chains of ...
