A paper titled "Functional implications of unusual NOS and SONOS covalent linkages found in proteins," by Matthew D. Lloyd, ...

It is weaker than a covalent bond and can be either inter- or intramolecular. Hydrogen bonds are responsible for the lattice structure of frozen water, for example, and for joining the two strands ...

Substances that consist of covalent molecules are usually gases or liquids at room temperature. Ionic bonds are formed between a metal and non-metal, for example, sodium chloride. Outer electrons ...

Uranium forms an unusually strong triple covalent bond with nitrile groups, confounding predictions about the bond strength of actinides compared with the remainder of the periodic table. Elements ...

Although drugs that make covalent bonds with their biological targets are as old as the pharmaceutical industry, intentionally designing molecules that make such bonds is relatively new.

Prior to 2000, many drugs that formed a covalent bond with targets did so non-selectively, which often led to undesired side effects when compared to non-covalent drugs. This led to the belief that ...
